3 Description

The

OPAx316-Q1

family

of

single

and

dual

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 suitable for

circuits requiring a good speed and power ratio. The

low input bias current supports those operational

amplifiers for applications with megaohm source

impedances. The low input bias current of the

OPAx316-Q1 yields a very-low current noise to make

the device attractive for high impedance sensor

interfaces.

The robust design of the OPAx316-Q1 provides ease-

of-use to the circuit designer: a unity-gain stable,

integrated RFI and 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

automotive grade operational amplifiers provide a

family of wide bandwidth, low noise, and low power

that meet the needs of a wide variety of applications.
