Product Summary

The op2177ARZ is a high precision, dual amplifier 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 op2177ARZ (dual) amplifier is available in tiny 8-lead surface-mount MSOP and 8-lead narrow SOIC packages. The op2177ARZ offers the widest specified temperature range of any high precision amplifier in surface-mount packaging. It is fully specified for operation from -40℃ to +125℃ for the most demanding operating environments.
