FEATURES  
DESCRIPTION  
The OPA322-Q1 family consists of single, dual, and  
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, and with a low  
quiescent current of only 1.5 mA per channel, these

Device HBM ESD Classification Level H3A  
Device CDM ESD Classification Level C5  
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-Q1 family ideal for a  
wide range of applications, including signal  
conditioning and sensor amplification requiring high  
gains. Featuring low THD+N, the OPA322-Q1 family  
is also excellent for consumer audio applications,  
particularly for single-supply systems.

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 (max)  
Supply Voltage: 1.8 V to 5.5 V  
Supply Current: 1.5 mA/ch  
The OPAx322S-Q1 models include a shutdown mode  
allowing the amplifiers to switch from normal  
operation to a standby current that is typically less  
than 0.1 μA.  
–
Shutdown: 0.1 μA/ch  
The OPA322-Q1 (single version) is available in  
SOT23-5 and SOT23-6, whereas the OPA2322 (dual  
version) comes in MSOP-8, MSOP-10, SO-8, and  
DFN-8 packages. The quad versions OPA4322 come  
in TSSOP-14 and TSSOP-16 packages. The  
specification on all versions is for operation from  
–40°C to 125°C.
