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.
Rev. E
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 pin compatible with the OP221, LM158,
MC1458/MC1558, and LT1013.
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.
