GENERAL DESCRIPTION
The OP200 is the first monolithic dual operational amplifier
to offer OP77 type precision performance. Available in the
industry standard 8-lead pinout, the OP200 combines precision
performance with the space and cost savings offered by a dual
amplifier.
The OP200 features an extremely low input offset voltage of
less than 75 μV with a drift below 0.5 μV/°C, guaranteed over
the full military temperature range. Open-loop gain of the OP200
exceeds 5,000,000 into a 10 kΩ load; input bias current is under
2 nA; CMRR is over 120 dB; and PSRR is below 1.8 μV/V. On-chip
Zener zap trimming is used to achieve the extremely low input
offset voltage of the OP200 and eliminates the need for offset
pulling.
Power consumption of the OP200 is low, with each amplifier
drawing less than 725 μA of supply current. The total current
drawn by the dual OP200 is less than one-half that of a single
OP07, yet the OP200 offers significant improvements over this
industry-standard op amp. The voltage noise density of the OP200,
11 nV/√Hz at 1 kHz, is half that of most competitive devices.
The OP200 is an ideal choice for applications requiring multiple
precision op amps and where low power consumption is critical.
For a quad precision op amp, see the OP400.
