GENERAL DESCRIPTION
The OPx177 family consists of very high precision, single, dual,
and quad amplifiers featuring extremely low offset voltage and
drift, low input bias current, low noise, and low power consump-
tion. Outputs are stable with capacitive loads of over 1000 pF
with no external compensation. Supply current is less than 500 μA
per amplifier at 30 V. Internal 500 Ω series resistors protect the
inputs, allowing input signal levels several volts beyond either
supply without phase reversal.
Unlike previous high voltage amplifiers with very low offset
voltages, the OP1177 (single) and OP2177 (dual) amplifiers
are available in tiny 8-lead surface-mount MSOP and 8-lead
narrow SOIC packages. The OP4177 (quad) is available in
TSSOP and 14-lead narrow SOIC packages. Moreover, specified
performance in the MSOP and the TSSOP is identical to
Rev. G

performance in the SOIC package. MSOP and TSSOP are
available in tape and reel only.
The OPx177 family offers the widest specified temperature
range of any high precision amplifier in surface-mount packaging.
All versions are fully specified for operation from −40°C to
+125°C for the most demanding operating environments.
Applications for these amplifiers include precision diode
power measurement, voltage and current level setting, and
level detection in optical and wireless transmission systems.
Additional applications include line-powered and portable
instrumentation and controls—thermocouple, RTD, strain-
bridge, and other sensor signal conditioning—and precision filters.
