OP200AZ Datasheet PDF - ADI

●Product Details

●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.
