The OP400HSZ-REEL is the first monolithic quad operational amplifier that features OP77-type performance. Precision performance is not sacrificed with the OP400HSZ-REEL to obtain the space and costsavings offered by quad amplifiers.
The OP400HSZ-REEL features an extremely low input offset voltage of less than 150 μV with a drift of less than 1.2 μV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP400HSZ-REEL is more than 5 million into a 10 kΩ load, input bias current is less than 3 nA, CMR is more than 120 dB, and PSRR is less than 1.8 μV/V. On-chip Zener zap trimming is used to achieve the low input offset voltage of the OP400HSZ-REEL and eliminates the need for offset nulling. The OP400HSZ-REEL conforms to the industrystandard quad pinout, which does not have null terminals.
The OP400HSZ-REEL features low power consumption, drawing less than 725 μA per amplifier. The total current drawn by this quad amplifier is less than that of a single OP07, yet the OP400HSZ-REEL offers significant improvements over this industry-standard op amp. Voltage noise density of the OP400HSZ-REEL is a low 11 nV/√Hz at 10 Hz, half that of most competitive devices.
The OP400HSZ-REEL is an ideal choice for applications requiring multiple precision operational amplifiers and where low power consumption is critical.
