Overview
The Texas Instruments OPA695IDR is a high-bandwidth, current-feedback operational amplifier designed to deliver exceptional performance and versatility. It combines an ultra-high slew rate of 4300 V/μs and low input voltage noise, making it ideal for high dynamic range applications. The OPA695IDR is optimized for high gain operation and is particularly suited for buffering surface acoustic wave (SAW) filters in intermediate frequency (IF) strips or delivering high output power at low distortion for cable-modem upstream line drivers. Its low power consumption and optional disable control feature make it suitable for a variety of applications, including portable instruments and broadband video line drivers.
