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.
FEATURES
* Single-Supply Operation: +3V ~ +5.5V
* Input / Output Rail-to-Rail
* Low Quiescent Current: 500μA @ 5V
* With Low Input Current
* 5.23V/μs High Slew Rate
* High Output Driving Capacity
* 6.5MHz High Gain-Bandwidth Product
* 70dB High PSRR
