PRODUCTION DATA. OPA322, OPA322S OPA2322, OPA2322S OPA4322, OPA4322S SBOS538F – JANUARY 2011 – REVISED DECEMBER 2016 OPAx322x 20-MHz, Low-Noise, 1.8-V, RRI/O, CMOS Operational Amplifier With Shutdown 1 1 Features 1 • Gain Bandwidth: 20 MHz • Low Noise: 8.5 nV √Hz at 1 kHz • Slew Rate: 10 V/μs • Low THD+N: 0.0005% • Rail-to-Rail I/O • Offset Voltage: 2 mV (maximum) • Supply Voltage: 1.8 V to 5.5 V • Supply Current: 1.5 mA/ch – Shutdown: 0.1 μA/ch • Unity-Gain Stable • Small Packages: – SOT-23, SON, VSSOP, TSSOP 2 Applications • Sensor Signal Conditioning • Consumer Audio • Multi-Pole Active Filters • Control-Loop Amplifiers • Communications • Security • Scanners Zero-Crossover Rail-to-Rail Input Stage Eliminates Distortion 3 Description The OPAx322x series consists of single, dual, and quad-channel CMOS operational amplifiers featuring low noise and rail-to-rail inputs and outputs optimized for low-power, single-supply applications. Specified over a wide supply range of 1.8 V to 5.5 V, the low quiescent current of only 1.5 mA per channel makes these devices well-suited for power-sensitive applications. The combination of very low noise (8.5 nV √Hz at 1 kHz), high-gain bandwidth (20 MHz), and fast slew rate (10 V/μs) make the OPAx322x family ideal for a wide range of applications, including signal conditioning and sensor amplification requiring high gains. Featuring low THD+N, the OPAx322x series is also excellent for consumer audio applications, particularly for single-supply systems. The OPAx322S models include a shutdown mode that allow the amplifiers to be switched from normal operation to a standby current that is typically less than 0.1 μA. The OPA322 (single version) is available in 5-pin SOT-23 and 6-pin SOT-23, while the OPA2322 (dual version) is offered in 8-pin VSSOP, 10-pin VSSOP, 8- pin SOIC, and 8-pin SON packages. The quad version OPA4322 comes in 14-pin TSSOP and 16-pin TSSOP packages. All versions are specified for operation from –40°C to +125°C.
