GENERAL DESCRIPTION

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 V

25 mV typical, a TCV

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 I

between amplifiers. These outstanding input current specifications

are realized through the use of a unique input current cancellation

circuit which typically holds I

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.
