RAIL TO RAIL I/O,

HIGH-SLEW-RATE OP AMP

DESCRIPTION

The UTC PA3211 is an input/output rail-to-rail operational

amplifier. This device can be operated on either a single supply

varying from +3V to +5.5V or dual supply ranging from ±1.5V to

±2.75V.

The UTC PA3211 has a perfect AC performance with 6.5MHz

bandwidth, 5.23V/μs slew rate.

The supply current for each amplifier of the UTC PA3211 is

only 500μA that makes it suitable for low current consumption

applications to control high current loads.

Applications include

audio amplification for computers, sound ports, sound cards and

set-top boxes.

The UTC PA3211 is generally applied in portable equipment,

headphone driver, multimedia audio, battery-powered equipment,

ASIC input or output amplifier, sensor amplifier, and low power/low

voltage device.
