APPLICATIONS
The ADA4077-1 and ADA4077-2 are available in an 8-lead SOIC
Process control front-end amplifiers package, including the B grade, and in an 8-lead MSOP (A grade
Optical network control circuits only). The ADA4077-4 is offered in a 14-lead TSSOP and a 14-lead
Instrumentation SOIC package.

GENERAL DESCRIPTION
160
The single ADA4077-1, dual ADA4077-2, and quad ADA4077-4
140
amplifiers feature extremely low offset voltage and drift, and low
120
input bias current, noise, and power consumption. Outputs are
100
stable with capacitive loads of more than 1000 pF with no
80
external compensation.
60
Applications for this amplifier include sensor signal conditioning
40
(such as thermocouples, resistance temperature detectors (RTDs),
strain gages), process control front-end amplifiers, and precision 20
diode power measurement in optical and wireless transmission
0
systems. The ADA4077-1/ADA4077-2/ADA4077-4 are useful in
V (V)
line powered and portable instrumentation, precision filters,
OS
and voltage or current measurement and level setting. Figure 4. Offset Voltage Distribution

Unlike other amplifiers, the ADA4077-1/ADA4077-2/
Op Amp First Second Third Fourth Fifth Sixth
ADA4077-4 have an MSL1 rating that is compliant with the most
Single OP07 OP77 OP177 OP1177 AD8677 ADA4077-1
stringent of assembly processes, and they are specified over the
Dual OP2177 ADA4077-2
extended industrial temperature range from 40C to +125C for
Quad OP4177 ADA4077-4
the most demanding operating environments.
