These amplifiers are designed for low-power data-acquisition systems and high-density applications where power dissipation is a critical parameter. The THS4521EVM is an evaluation module (EVM) for the single version, THS4521, in an SO-8 (D) package. The THS4522EVM is an evaluation module for the dual version, THS4522, in a TSSOP-16 (PW) package. The THS4524EVM is an evaluation module for the quad version, THS4524, in a TSSOP-32 (DBT) package. The THS4521/2/4EVMs are designed to quickly and easily demonstrate the functionality and versatility of these amplifiers. Each EVM is ready to connect to power, a signal source, and a variety of test instruments through the use of onboard connectors. The default amplifier configuration for each module is a single-ended input, single-ended output (via transformer), and split-supply operation. The EVMs can be easily configured for differential input, differential output, and single-supply operation. Throughout this document, the acronym EVM and the phrases evaluation module and evaluation board are synonymous with the THS4521/2/4EVMs. For clarity of reading, the abbreviation THS4521/2/4EVMs refers to the THS4521EVM, THS4522EVM, and THS4524EVM, unless otherwise noted. The electrical specifications for the THS4521/2/4EVMs are summarized in Table 1. Table 1. EVM Specifications 2 Parameter Units Single-supply voltage range (VS- = ground) 2.5 V to 5.5 V Split Supply voltage range (VS) 1.25 V to 2.75 V Supply current (IS) 1.1 mA/A, typ THS4521/2/4EVM Input voltage (VI) VS, max Output drive (IO) 55 mA, typ SBOU080 - July 2009 Submit Documentation Feedback Power Connections www.ti.com 2 Power Connections The THS4521/2/4EVMs are equipped with banana jacks for easy power connections. The positive supply input is labeled VS+. The negative supply input is labeled VS-. Ground is labeled GND. 2.1 Split-Supply Operation For split-supply operation, apply the positive supply voltage to VS+, the negative supply voltage to VS-, and the ground reference from supply to GND. 2.2 Single-Supply Operation For single-supply operation, connect VS- to GND with a jumper, and apply the positive supply voltage to VS+. 3 Input and Output Connections The THS4521/2/4EVMs are equipped with SMA connectors for easy connection of signal generators and analysis equipment. As shipped from the factory, the EVMs are configured for single-ended input and output with termination for connection to 50- test equipment. For best results, the signal should be routed to and from the EVM with cables that have 50- characteristic impedance. Refer to the THS4521, THS4522, THS4524 product data sheet, and the schematics and layouts provided in this user guide for details on how to reconfigure the EVM board for differential input or output operation. 3.1 Power-Down Operation The THS4521/2/4EVMs enable normal operation of the respective devices, or they can each be placed into a power-down mode through the placement of jumpers, as shown in Table 2.

Persons handling the product(s) must have electronics training and observe good engineering practice standards. As such, the goods being provided are not intended to be complete in terms of required design-, marketing-, and/or manufacturing-related protective considerations, including product safety and environmental measures typically found in end products that incorporate such semiconductor components or circuit boards. This evaluation board/kit does not fall within the scope of the European Union directives regarding electromagnetic compatibility, restricted substances (RoHS), recycling (WEEE), FCC, CE or UL, and therefore may not meet the technical requirements of these directives or other related directives. Should this evaluation board/kit not meet the specifications indicated in the User's Guide, the board/kit may be returned within 30 days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE. The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all claims arising from the handling or use of the goods. Due to the open construction of the product, it is the user's responsibility to take any and all appropriate precautions with regard to electrostatic discharge. EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES. TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive. TI assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. Please read the User's Guide and, specifically, the Warnings and Restrictions notice in the User's Guide prior to handling the product. This notice contains important safety information about temperatures and voltages. For additional information on TI's environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh. No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or combination in which such TI products or services might be or are used. FCC Warning This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference. EVM WARNINGS AND RESTRICTIONS It is important to operate this EVM within the input voltage range of 0 V to 5.5 V and the output voltage range of 3 V to 5.5 V. Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than +85C. The EVM is designed to operate properly with certain components above +85C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
