Evaluates: MAX4231 General Description Evaluates: MAX4231 MAX4231 Evaluation Kit Quick Start * MAX4231 EV kit * 5V, 1A power supply * Waveform generator * Oscilloscope Required Equipment Procedure The MAX4231 EV kit is fully assembled and tested. Follow the steps below to verify board operation. VSS1- VSS4 connectors are connected to the ground on the EV board. 1) Verify that all jumpers are in their default positions, as shown in Table 1. 2) Set the power-supply output to 5V. Disable the output. 3) Set the waveform-generator output to 1kHz sine wave, VP-P = 4V, offset = 2V. Disable the output. 4) Connect the power-supply output to the VDD connector. 5) Connect the power-supply ground to the VSS4 connector. 6) Connect the waveform-generator output to the VIN1 connector. 7) Connect the waveform-generator ground to the VSS1 connector. 8) Connect the positive input of the oscilloscope (channel 1) to the VIN1 connector. 9) Connect the negative input of the oscilloscope (channel 1) to the VSS1 connector. 10) Connect the positive input of the oscilloscope (channel 2) to the VOUT connector. 11) Connect the negative input of the oscilloscope (channel 2) to the VSS3 connector. 12) Enable the power-supply output. 13) Enable the waveform-generator output. 14) Verify that channel 1 and channel 2 have the identical waveform, both amplitude and phase. Detailed Description of Hardware The MAX4231 EV kit provides a proven layout for the MAX4231 single, high-output-drive CMOS op amp. The MAX4231 features 200mA of peak output current, rail-torail input and output capability from a single 2.7V to 5.5V supply. The amplifier exhibits a high slew rate of 10V/ Fs and a gain-bandwidth product (GBWP) of 10MHz. The MAX4231 also offers a SHDN feature that drives the output low. 2 _______________________________________________________________________________________ MAX4231 Evaluation Kit JUMPER JU1 JU2 JU3 SHUNT POSITION 1-2* Open 1-2* Open JU6 JU7 JU8 DC-blocking capacitor C2 bypassed DC-blocking capacitor C2 applied VIN1 applied to IN+ through R1 2-3 GND applied to IN+ through R1 No signal applied to IN+ through R1 1-2* VIN2 applied to IN- through R3 2-3 GND applied to IN- through R3 Open JU5 DC-blocking capacitor C1 applied 1-2* Open JU4 DESCRIPTION DC-blocking capacitor C1 bypassed No signal applied to IN- through R3 1-2 Zener voltage (2V nominal) applied to IN+ through R2 2-3* GND applied to IN+ through R2 Open No signal applied to IN+ through R2 1-2* DC-blocking capacitor C3 bypassed Open DC-blocking capacitor C3 applied 1-2* MAX4231 in normal operation mode 2-3 MAX4231 in shutdown mode 1-2* VDD applied to the output through R6 2-3 GND applied to the output through R6 *Default position. _______________________________________________________________________________________ 3 Evaluates: MAX4231 Table 1.
