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