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, resistance temperature detectors (RTDs),

strain gages), process control front-end amplifiers, and precision

diode power measurement in optical and wireless transmission

systems. The ADA4077-1/ADA4077-2/ADA4077-4 are useful in

line powered and portable instrumentation, precision filters,

and voltage or current measurement and level setting.

Figure 4. Offset Voltage Distribution

Table 1. Evolution of Precision Devices by Generation

Unlike other amplifiers, 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.
