3 Description

The OPAx314-Q1 series is a family of single–, and

dual–, and quad-channel operational amplifiers (op

amps) that represents a new generation of lowpower,

general-purpose CMOS amplifiers. Rail-to-rail

input and output swings, low quiescent current (150

μA typically at 5 VS) combined with a wide bandwidth

of 3 MHz, and very low noise (14 nV/√Hz at 1 kHz)

make this device family very attractive for a variety of

battery-powered applications that require a good

balance between cost and performance. The lowinput

bias current supports applications with

megaohm source impedances.

The robust design of the OPAx314-Q1 series

provides ease-of-use to the circuit designer: unitygain

stability with capacitive loads of up to 300 pF, an

integrated RF and EMI rejection filter, no phase

reversal in overdrive conditions, and high electrostatic

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

The device is optimized for low-voltage operation as

low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V), and

is specified over the full extended temperature range

of –40°C to +125°C.

The single-channel device, OPA314-Q1, is offered in

the SOT-23 package and the dual-channel device,

OPA2314-Q1, is offered in the VSSOP (8) package.

The quad-channel OPA4314-Q1 is available in the

14-pin TSSOP package.
