The OPA695 is a high bandwidth, current-feedback operational amplifier that combines an exceptional 5000V/µs slew rate and a low input voltage noise to deliver a precision, low-distortion, high dynamic range amplifier for use as intermediate gain stages in high-speed instrumentation systems. The OPA695 is optimized for high gain operation and is an excellent choice for interfacing current DAC output, or as gain stage in high-speed digitizers, or for delivering high output power at low distortion for cable-modem upstream line drivers.

The OPA695 features a low supply current of 14mA (at 25°C). System power can be further reduced using the optional disable control pin. Leaving this pin open, or holding this pin high, gives normal operation. If pulled low, the OPA695 supply current drops to less than 160µA. This power-saving feature, along with exceptional single 5V operation and ultra-small SOT23-6 packaging, make the OPA695 an excellent choice for portable applications.

The OPA695 is characterized for operation over the wide temperature range of –40°C to +85°C
