Precision Low Noise Operational Amplifier
ISL76627
The ISL76627 is a very high precision amplifier featuring very low
noise, low offset voltage, low input bias current and low
temperature drift making it the ideal choice for applications
requiring both high DC accuracy and AC performance. The
combination of precision, low noise, and small footprint provides
the user with outstanding value and flexibility relative to similar
competitive parts.
Applications for ISL76627 include precision active filters,
precision power supply controls, data acquisition signal
conditioning, sensor interface, instrumentation and high grade
audio.
Of particular interest for automotive applications is the wide
range operating voltage of this op-amp combined with the
combination of precision and speed.
The ISL76627 is available in an 8 Ld SOIC package. The device is
offered in standard pin configurations and operates over the
extended temperature range of -40°C to +125°C.
The ISL76627 is fully TS16949 compliant and tested to
AEC-Q100 specifications.
