OPA657U Description

Short technical summary and product information.

The OPA657U from Texas Instruments is a high-speed, low-noise, FET-input operational amplifier designed for high dynamic range applications. It combines a high-gain bandwidth voltage-feedback amplifier with a low-voltage noise JFET input stage.

Key electrical characteristics include a 1.6 GHz gain bandwidth product and a 275 MHz bandwidth at a gain of 10. The device boasts a high slew rate of 700 V/µs (G=10, 1-V step) and a low input offset voltage of ±250 µV. With a low input bias current of 2 pA and low input voltage noise of 4.8 nV/√Hz, it excels in amplifying very low-level signals.

This operational amplifier is well-suited for high-precision analog-to-digital converter (ADC) driving or wideband transimpedance applications. Its decompensated, high-gain bandwidth design also provides improved noise and bandwidth for photodiode applications.

The OPA657U is available in an 8-pin SOIC package and operates within a temperature range of -40°C to 85°C. It is supplied in a tube with 75 units per package.
