Dual, Low Noise, Low Offset Instrumentation Operational Amplifier - Analog Devices

The OP227 is the first dual Amplifier to offer a combination of low offset, low noise, high speed, and guaranteed Amplifier matching characteristics in one device. The OP227 with a VOS match of 25 mV typical, a TCVOS match of 0.3 mV/C typical and a 1/f corner of only 2.7 Hz is an excellent choice for precision low noise designs. These dc characteristics, coupled with a slew rate of 2.8 V/ms typical and a small-signal bandwidth of 8 MHz typical, allow the designer to achieve ac performance previously unattainable with op amp based instrumentation designs. When used in a three op amp instrumentation configuration, the OP227 CAN achieve a CMRR in excess of 100 dB at 10 kHz. In addition, this device has an open-loop gain of 1.5 M typical with a 1 kW load. The OP227 also features an IB of 10 nA typical, an IOS of 7 nA typical, and guaranteed matching of input currents between Amplifiers These outstanding input current specifications are realized through the use of a unique input current cancellation circuit which typically holds IB and IOS to 20 nA and 15 nA respectively over the full military temperature range. Other sources of input referred errors, such as PSRR and CMRR, are reduced by factors in excess of 120 dB for the individual Amplifiers DC stability is assured by a long-term drift application of 1.0 mV/month. Matching between channels is provided on all critical param- eters including offset voltage, tracking of offset voltage versus temperature, noninverting bias current, CMRR, and power supply rejection ratio. This unique dual Amplifier allows the elimination of external components for offset nulling and frequency compensation. By Analog Devices, Inc.
