6.1 Overview

The OPA695 is a high-speed current-feedback amplifier (CFA) designed to operate over a wide supply range of ±2.5 V (5 V) to ±6 V (12 V) for applications requiring low distortion along with wide-bandwidth and high slew-rate. Common applications for current-feedback operational amplifiers include gain blocks in high-speed data-acquisition systems, coaxial cable drivers, analog-to-digital converter (ADC) drivers, and digital-to-analog converters(DAC) drivers. The OPA695 features a power-down pin that puts the amplifier in low-power standby mode and lowers the quiescent current from 14 mA to 160 µA.
