OP777ARM

The OP777ARM belongs to OP777 family which is a precision single supply amplifier featuring micropower operation and rail-to-rail output ranges and the OP777 is specified over the extended industrial (-40°C to +85°C) temperature range and is available in 8-lead MSOP and 8-lead SOIC packages. The OP777 uses a standard operational amplifier pinout, allowing for easy drop-in replacement of lower performance amplifiers in most circuits. Surface mount devices in MSOP packages are available in tape and reel only The specially fabricated input PNP transistors operate with very low input bias currents while allowing operation with large differential voltages, eliminating a common limitation of many precision amplifiers and enabling application of the OP777 in precision comparator and rectifier circuits. This large differential voltage capability also further reduces the need for external protection devices such as clamping diodes. The proprietary fabrication process yields a very low-voltage noise corner frequency under 10 Hz, greatly improving the low-frequency noise perfor- mance of the OP07 and similar amplifiers. Applications for these amplifiers portable instrumentation, remote precision filters. include both line powered and sensor signal conditioning. This amplifier provides improved performance over the industry-standard OP07 with ±15 V supplies and offers the further advantage of true single supply operation down to 2.7V and smaller package footprint than any other high-voltage precision bipolar amplifier. Outputs are stable with capacitive loads of over 1000 pF. Supply current is less than 30A per amplifier at 5 V. 500 S2 series resistors protect the inputs, allowing input signal levels to exceed either power supply rail by up to 3 V without causing phase reversal of the output signal or causing damage to the amplifier.

The features of OP777ARM can be summarized as (1)low offset voltage: 100 V Max; (2)low input bias current: 10 nA Max; (3)single-supply operation: 2.7 V to 30 V; (4)dual-supply operation: ±1.35 V to ±15V; (5)low supply current: 300 A/Amp Max; (6)unity gain stable; (7)no phase reversal.
