Precision, 20MHz, 0.9pA, Low-Noise, RRIO,

CMOS Operational Amplifier with Shutdown

Check for Samples: OPA320, OPA2320, OPA320S, OPA2320S

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.

•

Precision with Zero-Crossover Distortion:

–

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.

–

I_Qin Shutdown Mode: 0.1μA

•

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.

APPLICATIONS

•

High-Z Sensor Signal Conditioning

Transimpedance Amplifiers

Test and Measurement Equipment

Programmable Logic Controllers (PLCs)

Motor Control Loops

The OPA320 (single version) is available in a

SOT23-5 package; the OPA320S shut-down single

version is available in an SOT23-6 package. The dual

OPA2320 is offered in SO-8, MSOP-8, and DFN-8

packages, and the OPA2320S (dual with shut-down)

in an MSOP-10 package.
