SLOS884 –SEPTEMBER 2014
OPA2320-Q1 Precision, 20-MHz, 0.9-pA, Low-Noise, RRIO,
CMOS Operational Amplifier
1 Features
3 Description
The OPA2320-Q1 device is a new generation of
precision low-voltage CMOS operational amplifiers
(op amps) optimized for very low noise and wide
bandwidth while operating on a low quiescent current
of only 1.45 mA.

converters (ADCs). Other applications include signal
conditioning and sensor amplification.
Rail-to-Rail I/O
The OPA2320-Q1 device features a linear input stage
with zero-crossover distortion that delivers excellent
common-mode rejection ratio (CMRR) of 114 dB
(typical) over the full input range. The input common-
mode range extends 100 mV beyond the negative
and positive supply rails. The output voltage typically
swings within 10 mV of the rails.

Low Input Bias Current: 0.9 pA (max)
Low Noise: 7 nV/vHz at 10kHz
Wide Bandwidth: 20 MHz
Slew Rate: 10 V/µs
Quiescent Current: 1.45 mA/ch
Single-Supply Voltage Range: 1.8 to 5.5 V
Unity-Gain Stable
In addition, the OPA2320-Q1 device has a wide
supply voltage range from 1.8 to 5.5 V with excellent
PSRR (106 dB) over the entire supply range, making
the device suitable for precision, low-power
applications that run directly from batteries without
regulation.
