1 / 38 page OPA322, OPA322S OPA2322, OPA2322S OPA4322, OPA4322S www.ti.com SBOS538E – JANUARY 2011 – REVISED JUNE 2012 20-MHz, Low-Noise, 1.8-V, RRI/O, CMOS Operational Amplifier with Shutdown Check for Samples: OPA322, OPA322S, OPA2322, OPA2322S, OPA4322, OPA4322S 1 FEATURES DESCRIPTION The OPA322 series consists of single, dual, and 23 • Gain Bandwidth: 20 MHz quad-channel CMOS operational amplifiers featuring • Low Noise: 8.5 nV/ √Hz at 1 kHz low noise and rail-to-rail inputs/outputs optimized for • Slew Rate: 10 V/ μs low-power, single-supply applications. Specified over a wide supply range of 1.8 V to 5.5 V, the low • Low THD+N: 0.0005% quiescent current of only 1.5 mA per channel makes • Rail-to-Rail I/O these devices well-suited for power-sensitive • Offset Voltage: 2 mV (max) applications. • Supply Voltage: 1.8 V to 5.5 V The combination of very low noise (8.5 nV/ √Hz at • Supply Current: 1.5 mA/ch 1 kHz), high gain-bandwidth (20 MHz), and fast slew rate (10 V/ μs) make the OPA322 family ideal for a – Shutdown: 0.1 μA/ch wide range of applications, including signal • Unity-Gain Stable conditioning and sensor amplification requiring high • Small Packages: gains. Featuring low THD+N, the OPA322 series is also excellent for consumer audio applications, – SOT23, DFN, MSOP, TSSOP particularly for single-supply systems. APPLICATIONS The OPAx322S models include a shutdown mode allowing the amplifiers to be switched from normal • Sensor Signal Conditioning operation to a standby current that is typically less • Consumer Audio than 0.1 μA. • Multi-Pole Active Filters The OPA322 (single version) is available in SOT23-5 • Control-Loop Amplifiers and SOT23-6, while the OPA2322 (dual version) is • Communications offered in MSOP-8, MSOP-10, SO-8, and DFN-8 packages. The quad versions OPA4322 come in • Security TSSOP-14 and TSSOP-16 packages. All versions are • Scanners specified for operation from –40°C to +125°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 FilterPro is a trademark of Texas Instruments Incorporated. 3 All other trademarks are the property of their respective owners.
