GENERAL DESCRIPTION
The OP400 is the first monolithic quad operational amplifier The OP400 features low power consumption, drawing less than that features OP77-type performance. Precision performance is 725 µA per amplifier. The total current drawn by this quad not sacrificed with the OP400 to obtain the space and cost amplifier is less than that of a single OP07, yet the OP400 offers savings offered by quad amplifiers. significant improvements over this industry-standard op amp. The OP400 features an extremely low input offset voltage of less Voltage noise density of the OP400 is a low 11 nV/√Hz at than 150 µV with a drift of less than 1.2 µV/°C, guaranteed over 10 Hz, half that of most competitive devices. the ful military temperature range. Open-loop gain of the The OP400 is an ideal choice for applications requiring multiple OP400 is more than 5 million into a 10 kΩ load, input bias precision operational amplifiers and where low power current is less than 3 nA, CMR is more than 120 dB, and PSRR consumption is critical. is less than 1.8 µV/V. On-chip Zener zap trimming is used to achieve the low input offset voltage of the OP400 and eliminates the need for offset nul ing. The OP400 conforms to the industry- standard quad pinout, which does not have null terminals.
