1 Dual Low Offset, Low Power Operational Amplifier OP200 FEATURES Low input offset voltage: 75 μv maximum Low offset voltage drift, over 55 C < TA < +25 C 0.5 μv/ C maximum Low supply current (per amplifier): 725 μa maximum High open-loop gain: 5000 V/mV minimum Low input bias current: 2 na maximum Low noise voltage density: nv/ Hz at khz Stable with large capacitive loads: 0 nf typical PIN CONNECTIONS IN A 6 OUT A +IN A 2 5 NC NC 3 4 NC V 4 3 V+ NC 5 2 NC +IN B 6 NC IN B 7 0 OUT B NC 9 NC NC = NO CONNECT Figure. 6-Lead SOIC (S-Suffix) GENERAL DESCRIPTION The OP200 is the first monolithic dual operational amplifier to offer OP77 type precision performance. Available in the industry standard -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 0 kω load; input bias current is under 2 na; CMRR is over 20 db; and PSRR is below. 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.

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, nv/ Hz at khz, is half that of most competitive devices. The OP200 is pin compatible with the OP22, LM5, MC45/MC55, and LT03. The OP200 is an ideal choice for applications requiring multiple precision op amps and where low power consumption is critical.
