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
