STEVAL-CCA022V1

in SC70 or SOT-23 packages

Data brief

Description

The STEVAL-CCA022V1 demonstration board is
designed to help characterize single operational
amplifiers in SOT23-5 (two different pinouts) and
SC70-5 packages.

Operational amplifiers in SOT23-6 and SC70-6
packages can also be characterized but their
standby pin is not usable because it is connected
to V

The STEVAL-CCA022V1 allows to characterize,
among the others, the following op-amps (not
included in the package): TS507, TSV621,
TSV631, TSV911, TSV991, TS1851, TS1871,
TS931, TS941, TS951, TS971, TS321.
