UNISONIC TECHNOLOGIES CO., LTD PA3211 Preliminary CMOS IC 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.
