Description and Introduction
Wideband Current Feedback Operational Amplifier with Disable 8-SOIC -40 to 85 The **OPA691IDG4** is a high-speed, wideband operational amplifier (op-amp) designed for precision signal conditioning and high-frequency applications. Manufactured by Texas Instruments, this component features a unity-gain bandwidth of **500 MHz** and a fast slew rate of **1800 V/µs**, making it well-suited for video processing, communications, and test equipment.  
With a low distortion profile and excellent linearity, the OPA691IDG4 ensures accurate signal amplification in demanding environments. Its **current-feedback architecture** allows for stable operation across a wide range of gains, while maintaining consistent bandwidth performance. The device operates on a **±5V to ±15V supply range**, providing flexibility in various circuit designs.   Housed in an **8-pin SOIC package**, the OPA691IDG4 offers a compact footprint for space-constrained applications. Key features include **low noise (2.7 nV/√Hz)** and high output current drive (±120 mA), enabling robust performance in both single-ended and differential configurations.   Engineers favor this op-amp for its reliability in high-speed data acquisition, active filtering, and RF signal processing. Its combination of speed, precision, and versatility makes it a preferred choice for advanced analog designs. |
