3 Description

The OPAx316 family of single, dual, and quad

operational amplifiers represents a new generation of

general-purpose, low-power operational amplifiers.

Featuring rail-to-rail input and output swings, low

quiescent current (400 μA/ch typical) combined with a

wide bandwidth of 10 MHz and very-low noise

(11 nV/√Hz at 1 kHz) makes this family attractive for

a variety of applications that require a good balance

between cost and performance. The low input bias

current supports those operational amplifiers to be

used in applications with MΩ source impedances.

The robust design of the OPAx316 provide ease-ofuse

to the circuit designer—a unity-gain stable,

integrated RFI-EMI rejection filter, no phase reversal

in overdrive condition, and high electrostatic

discharge (ESD) protection (4-kV HBM).

These devices are optimized for low-voltage

operation as low as 1.8 V (±0.9 V) and up to 5.5 V

(±2.75 V). This latest addition of low-voltage CMOS

operational amplifiers, in conjunction with the

OPAx313 and OPAx314 provide a family of

bandwidth, noise, and power options to meet the

needs of a wide variety of applications.
