Description
The TS9222 and TS9224 are rail-to-rail dual and
quad operational amplifiers optimized for
precision, noise and stability, which make them
suitable for a wide range of automotive and
industrial applications.
These devices deliver a high output current that
allows low-load impedances to be driven. They
are stable for capacitive loads up to 500 pF.
