Quick Start
Required Equipment
• MAX4231 EV kit
• 5V, 1A power supply
• Waveform generator
• Oscilloscope
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 out-
put.
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 identi-
cal 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-to-
rail 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.
