1 General Description
The AS1710/AS1712 are low-offset, high-output CMOS op-amps
that deliver 200mA of peak output current from a single supply (2.7V
to 5.5V).
These devices were specifically designed to drive typical headset
levels (32), as well as bias RF power amplifiers for wireless
handset applications.
