• Consumer Audio
• Multi-Pole Active Filters
• Control-Loop Amplifiers
• Communications
• Security
• Scanners
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 OPAx322-Q1 family ideal for
a wide range of applications, including signal
conditioning and sensor amplification requiring high
gains. Featuring low THD+N, the OPAx322-Q1 family
is also excellent for consumer audio applications,
particularly for single-supply systems.
The OPA322-Q1 (single version) is available in 5-pin
SOT-23 package, while the OPA2322-Q1 (dual
version) is offered in a 8-pin VSSOP package. The
OPA4322-Q1 (quad version) is available in a 14-pin
TSSOP package. All versions are specified for
operation from –40°C to +125°C.

3 Description
The OPAx322-Q1 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 from 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.
