Introduction
The ISL2829xEVAL1Z, ISL5529xEVAL1Z evaluation board
is a design platform containing all the circuitry needed to
characterize critical performance parameters of the
ISL28290, ISL28291, ISL55290 and ISL55291 dual op
amps, using a variety of user defined test circuits.
The ISL2829x and ISL5529x amplifiers are dual high speed
operational amplifiers featuring low noise, low distortion, and
rail-to-rail output drive capability. They are designed to
operate with single and dual supplies from +5V (±2.5V)
down to +3V (±1.5V).

Evaluation Board Key Features
The ISL2829xEVAL1Z, ISL5529xEVAL1Z is designed to
enable the IC to operate from a single supply (+3V to +5V),
or from split supplies (±1.5V to ±2.5V). Each op amp in the
dual package is independently configured for differential
input and for a closed loop gain of 10.
Power Supplies
External power connections are made through the V
and Ground connections on the evaluation board. For single
supply operation, the V

Amplifier Configuration
The schematic of each of the 2 op amps with the
components supplied is shown in Figure 2. The op amp is
configured for low impedance, high speed inputs, and
included additional component pads to enable the user to
change the input characteristics to suit the application. A
series 50Ω back-termination is included for stable operation
when driving 50Ω cables.
User-Selectable Options
Component pads are included to enable a variety of
user-selectable circuits to be added to the amplifier inputs,
