3 Description

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
