Product Overview
The OPA657 is a Texas Instruments FET-input operational amplifier in the Signal_Chain category. Its extracted electrical data identifies a high-speed amplifier with 1.6 GHz gain bandwidth product under G > +40 V/V, VS = ±15 V, TJ = 25°C conditions, plus gain-dependent small-signal bandwidth ratings of 350 MHz, 275 MHz, and 90 MHz.
Dynamic specifications include 180 MHz large-signal bandwidth at G = +10 V/V and 2 VPP output, 30 MHz bandwidth for 0.1 dB flatness under the same gain and output level, 700 V/µs slew rate, 1 ns rise and fall time, and 20 ns settling time to 0.02% for a 2 V step.
The amplifier is available in SOT-23-5 2.90 mm x 1.60 mm and SOIC-8 4.90 mm x 3.91 mm packages. Recommended operation covers total supply voltage from 8 V to 12 V and ambient temperature from -40°C to 85°C. The FET-input characteristics support low input current use cases, with input current noise specified at 1.3 fA/√Hz and input bias current specified down to typ ±1 pA for the high-grade DC specification.
