OPA375 (ACTIVE)

OPAx375, 500uV, 10-MHz, Low Broadband Noise, RRO, Operational Amplifier

 

Description

The OPA375 operational amplifier (op amp) is a general-purpose CMOS op amp that provides low noise of 3.7 nV/√Hz low offset of 500 µV (maximum) and a wide bandwidth of 10 MHz. The low noise and wide bandwidth make the OPA375 device attractive for a variety of precision applications that require a good balance between cost and performance. Additionally, the input bias current of the OPA375 supports applications with high source impedance.

The robust design of the OPA375 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 (1-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) and up to 5.5 V (±2.75 V), and is specified over the temperature range of –40°C to +125°C.

The single-channel OPA375 is available in a small-size SC70-5 package.
