GENERAL DESCRIPTION
The single ADA4077-1, dual ADA4077-2, and quad ADA4077-4
amplifiers feature extremely low offset voltage and drift, and low
input bias current, noise, and power consumption. Outputs are
stable with capacitive loads of more than 1000 pF with no
external compensation.
Applications for this amplifier include sensor signal conditioning
(such as thermocouples, RTDs, strain gauges), process control
front-end amplifiers, and precision diode power measurement
in optical and wireless transmission systems. The ADA4077-1,
ADA4077-2, and ADA4077-4 are useful in line powered and
portable instrumentation, precision filters, and voltage or
current measurement and level setting.
Unlike amplifiers by some competitors, the ADA4077-1/
ADA4077-2/ADA4077-4 have an MSL1 rating that is compliant
with the most stringent of assembly processes, and they are
specified over the extended industrial temperature range from
−40°C to +125°C for the most demanding operating environments.
