FEATURES
DESCRIPTION
The OPA320 (single) and OPA2320 (dual) are a new
generation of precision, low-voltage CMOS
operational amplifiers optimized for very low noise
and wide bandwidth while operating on a low
quiescent current of only 1.45mA.

Low Offset Voltage: 150μV (max)
High CMRR: 114dB
Rail-to-Rail I/O
•
Low Input Bias Current: 0.9pA (max)
Low Noise: 7nV/√Hz at 10kHz
Wide Bandwidth: 20MHz
The OPA320 series is ideal for low-power,
single-supply applications. Low-noise (7nV/√Hz) and
high-speed operation also make them well-suited for
driving sampling analog-to-digital converters (ADCs).
Other applications include signal conditioning and
sensor amplification.

Slew Rate: 10V/μs
Quiescent Current: 1.45mA/ch
Single-Supply Voltage Range: 1.8V to 5.5V
OPA320S, OPA2320S:
The OPA320 features a linear input stage with
zero-crossover distortion that delivers excellent
common-mode rejection ratio (CMRR) of typically
114dB over the full input range. The input
common-mode range extends 100mV beyond the
negative and positive supply rails. The output voltage
typically swings within 10mV of the rails.

Unity-Gain Stable
Small Packages:

SOT23, MSOP, DFN
In addition, the OPAx320 have a wide supply voltage
range from 1.8V to 5.5V with excellent PSRR (106dB)
over the entire supply range, making them suitable
for precision, low-power applications that run directly
from batteries without regulation.
