Evaluation Board User’s Guide
Introduction
The ISL28433SOICEVAL1Z and ISL28433TSSOPEVAL1Z
Evaluation Board is designed to evaluate the performance
of the ISL28433 Chopper Stabilized op amp. The evaluation
board contains the circuitry needed to evaluate the high
performance of the ISL28433 amplifier. The ISL28433
chopper stabilized rail-to-rail quad op amp features a low
8μV maximum V OS over-temperature and a 0.1Hz 1/f
noise corner frequency enabling very high gain single-stage
DC amplifiers that can operate from single cell batteries
while consuming only 20μA of current. The
ISL28433SOICEVAL1Z and ISL28433TSSOPEVAL1Z
evaluation board can be configured as a precision high-gain
(G = 10,000V/V) differential amplifier and demonstrates
the level of performance possible with this type of amplifier
while operating from battery voltages as low as 1.65V.

Power Supplies (Figure 1)
External power connections are made through the V+,
V-, VREF, and GND connections on the evaluation board.
The circuit can operate from a single supply or from dual
supplies. For single supply operation, the V- and GND
pins are tied together to the negative or ground
reference of the power supply. For split supplies, V+ and
V- terminals connect to their respective supply terminals.
De-coupling capacitors C1 and C2 provide low-frequency
power-supply filtering, while additional capacitors, C3
and C4, which are connected close to the part, filter out
high frequency noise. Anti-reverse diodes D1 and D2
(optional) protects the circuit in the momentary case of
accidentally reversing the power supplies to the
evaluation board. The VREF pin can be connected to
ground to establish a ground referenced input for split
supply operation, or can be externally set to any
reference level for single supply operation.
