FEATURES

DESCRIPTION

The OPA322 series consists of single, dual, and

•

Gain Bandwidth: 20 MHz

Low Noise: 8.5 nV/√Hz at 1 kHz

Slew Rate: 10 V/μs

quad-channel CMOS operational amplifiers featuring

low noise and rail-to-rail inputs/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.

•

Low THD+N: 0.0005%

Rail-to-Rail I/O

Offset Voltage: 2 mV (max)

Supply Voltage: 1.8 V to 5.5 V

Supply Current: 1.5 mA/ch

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 OPA322 family ideal for a

wide range of applications, including signal

conditioning and sensor amplification requiring high

gains. Featuring low THD+N, the OPA322 series is

also excellent for consumer audio applications,

particularly for single-supply systems.

–

Shutdown: 0.1 μA/ch

•

Unity-Gain Stable

Small Packages:

–

SOT23, DFN, MSOP, TSSOP

APPLICATIONS

The OPAx322S models include a shutdown mode

allowing the amplifiers to be switched from normal

operation to a standby current that is typically less

than 0.1 μA.

Sensor Signal Conditioning

Consumer Audio

Multi-Pole Active Filters

Control-Loop Amplifiers

Security

The OPA322 (single version) is available in SOT23-5

and SOT23-6, while the OPA2322 (dual version) is

offered in MSOP-8, MSOP-10, SO-8, and DFN-8

packages. The quad versions OPA4322 come in

TSSOP-14 and TSSOP-16 packages. All versions are

specified for operation from –40°C to +125°C.
