OPA637AU Description

Short technical summary and product information.

The OPA637AU from Texas Instruments is a precision, high-speed operational amplifier designed for demanding applications. It features a single channel and operates with a total supply voltage ranging from 9V to 36V.

 

Key electrical characteristics include a typical gain bandwidth product of 80 MHz and a high slew rate of 135 V/µs. The device exhibits a low offset voltage of 0.1 mV (max) at 25°C and a typical offset drift of 0.4 µV/°C. Input bias current is a maximum of 5 pA, and noise voltage at 1 kHz is typically 5.2 nV/√Hz. The Common Mode Rejection Ratio (CMRR) is typically 110 dB.

 

This operational amplifier is housed in a SOIC (D) package with dimensions of 4.9 mm x 6 mm, covering an area of 29.4 mm². It is rated for an operating temperature range of -25°C to 85°C. The OPA637AU is noted as 'Decompensated' and does not feature rail-to-rail output.

 

Note: This part is not recommended for new designs.
