100

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.

(µV)

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.
