Description for the OPA375
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.
