GENERAL DESCRIPTION
The OP400 is the first monolithic quad operational amplifier
that features OP77 type performance. Precision performance no
longer has to be sacrificed to obtain the space and cost savings
offered by quad amplifiers.
The OP400 features an extremely low input offset voltage of
less than 150 mV with a drift of under 1.2 mV/∞C, guaranteed
over the full military temperature range. Open-loop gain of the
OP400 is over 5,000,000 into a 10 kW load, input bias current is
under 3 nA, CMR is above 120 dB, and PSRR is below 1.8 mV/V.
On-chip zener-zap trimming is used to achieve the low input
offset voltage of the OP400 and eliminates the need for offset
nulling. The OP400 conforms to the industry-standard quad
pinout which does not have null terminals.

The OP400 features low power consumption, drawing less than
725 mA per amplifier. The total current drawn by this quad
amplifier is less than that of a single OP07, yet the OP400 offers
significant improvements over this industry standard op amp.
Voltage noise density of the OP400 is a low 11 nV/
which is half that of most competitive devices.
The OP400 is pin-compatible with the LM148, HA4741,
RM4156, and LT1014 operational amplifiers and can be used
to upgrade systems using these devices. The OP400 is an ideal
choice for applications requiring multiple precision operational
amplifiers and where low power consumption is critical.
