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 (2.7 to 5.5V).
These devices were specifically designed to drive typical headset levels (32Ω), as well as bias RF power amplifiers for wireless handset applications.
