OPA2320-Q1

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.

•

Qualified for Automotive Applications

AEC-Q100 Qualified with the Following Results:

–

Device Temperature Grade 1: –40°C to 125°C

Ambient Operating Temperature Range

–

Device HBM ESD Classification Level 2

Device CDM ESD Classification Level C4B

The OPA2320-Q1 device is ideal for low-power,

single-supply applications. Low-noise (7 nV/vHz) and

high-speed operation also makes the device well-

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.
