3 Description

The OPAx375 family includes single (OPA375), dual

(OPA2375) and quad-channel (OPA2375) general-

purpose CMOS operation amplifiers (op amp) that

provide an extremely low noise figure of 3.5 nV/√Hz, a

low offset of 500 µV (maximum) and a wide bandwidth

of 10 MHz. The low noise and wide bandwidth make

the OPAx375 family attractive for a variety of precision

applications that require a good balance between

cost and performance. Additionally, the input bias

current of the OPAx375 supports applications with

high source impedance.

The robust design of the OPAx375 family provides

ease-of-use to the circuit designer due to the unity-

gain stability, integrated RFI/EMI rejection filter, no

phase reversal in overdrive conditions, and high

electrostatic discharge (ESD) protection (2-kV HBM).

Additionally, the resistive open-loop output impedance

allows for easy stabilization with much higher

capacitive loads.

This op amp is optimized for low-voltage operation

as low as 2.25 V (±1.125 V) for the OPA375 and

1.7 V (±0.85 V) for the OPA2375 and OPA4375. All

of the devices operate up to 5.5 V (±2.75 V), and

are specified over the temperature range of –40°C to

125°C.

The single-channel OPA375 is available in a small-

size SC70-5 package. The dual-channel OPA2375 is

available in multiple package options including a tiny

1.5 mm × 2.0 mm X2QFN package.
