OP4177

Precision Low Noise, Low Input Bias Current Quad Op Amp
Manufactured by:

Product Details

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 consumption. 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 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.

We choose this AD op amp for a project, which is supposed to work in high noisy and high input impedance atmosphere. i discarded many op amps due to there poor performance at noisy atmosphere. Performance of OP4177 is very good and i am so satisfied.

OP4177
The op-amp is a decent choice for low power application, and the performance is fair. I tried several Op-amps and the 4177 is very good for our design.

temperature tests
Did high temperature test 25C--150C--25C using different parts from different companies. Analog Devices - AD8634, OP4177, OP491. the parts have great low temperature drift performance. And showed good high temperature drift performance. in all we are satisfited with results.
