Overview
The OPA857EVM is an evaluation module for the OPA857 amplifier in a QFN-16 (RGT) package. This
evaluation module is designed to quickly and easily demonstrate the functionality and versatility of the
amplifier. The EVM is ready to connect to power, signal source, and test instruments through the use of
onboard connectors. The EVM comes configured for easy connection with common 50-Ω laboratory
equipment on its inputs and outputs. The amplifier is configured for a single-ended input with a selectable
transimpedance gain (5 kΩ or 20 kΩ). The pseudo-differential output at the device pins is then converted
to a single-ended signal through an RF transformer.

Description
Power Connections
The OPA857EVM is equipped with banana jacks for connecting the power supply and GND. These jacks
are labeled VCC and GND, respectively. Appropriate power-supply bypassing is installed. To power-up
the OPA857EVM, connect jumper J7 to GND, and apply the positive supply voltage to VS+ through J6. For
proper operation, the inputs and outputs must be biased per the data sheet specifications.
5
Transimpedance Control
Transimpedance gain can be controlled in multiple ways. This gain can be manually controlled through a
3-position jumper (JP2), which is connected to either VCC or GND. Alternatively, gain can be programmed
through the SMA connector J10. Remember to remove the JP2 jumper shunt when controlling gain
through programming.
6
Test_SD
This pin can be controlled manually through jumper JP1.
7
Test_In
This pin can be driven through the SMA connector J1. In test mode, set the dc bias of the input signal to
approximately 2.1 V. The output test current, IOUT is approximately VTest_In(AC) / 2 kΩ.
8
Input and Output Connections
The input to the OPA857 is applied through the SMA connector J2. The OPA857 can be configured as a
traditional TIA by installing a 0-Ω resistor in place of R4. Alternatively, the device can be configured in an
inverting op amp configuration by installing a resistor of the desired size at R4. The pseudo-differential
output of the OPA857 can be measured through jumpers J4 and J5. Alternatively, the output can be
converted to a single-ended signal by the RF transformer T1, and measured at the SMA connector J3.
Note that the OUT and OUTN pins have internal 25-Ω resistors on each pin; take these resistors into
account during gain calculations when loading the amplifier.
