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 amplifi-
ers for wireless handset applications.
The devices are available as the standard products

These rail-to-rail I/O, wide-bandwidth amplifiers exhibit a
high slew rate of 10V/µs and a gain-bandwidth product
of 10MHz.
The integrated shutdown feature (not included in B ver-
sions) drives the output low.
These devices operate over the entire automotive tem-
perature range (-40°C to +125°C).
3 Applications
The devices are ideal for portable/battery-powered
audio applications, portable headphone speaker drivers
(32Ω), hands-free mobile phone kits, TFT panels, sound
ports/cards, set-top boxes, biasing controls, DAC con-
verter buffers, transformer/line drivers, motor drivers,
and any other battery-operated audio device.
