The Texas Instruments OPA657NB/250 is a high-speed, low-noise operational amplifier featuring a FET input and a voltage feedback architecture. It boasts a high gain bandwidth product of 1.6 GHz and a fast slew rate of 700 V/µs, making it suitable for high-frequency applications.
This amplifier operates over a total supply voltage range of 8 V to 12 V and features a low input offset voltage of ±250 µV and low input bias current of 2 pA. The OPA657NB/250 also provides a high output current of 70 mA and exhibits excellent harmonic distortion performance, with 2nd harmonic at 74 dBc and 3rd harmonic at 106 dBc at 5 MHz.
Available in SOIC (D) and SOT-23 (DBV) packages, the OPA657NB/250 is rated for an operating temperature range of -40°C to 85°C. Its design considerations include its decompensated nature and suitability for applications requiring high speed and precision.
Key specifications include a 1.6 GHz gain bandwidth product, 350 MHz bandwidth at a gain of 10, and a minimum stable gain of 7 V/V. The input voltage noise density is 4.8 nV/√Hz at flatband and 7 nV/√Hz at 1 kHz.
