Available in the industry standard 8-pin 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 mV with a drift below 0.5 mV/∞C, guaranteed over the full military temperature range. Open-loop gain of the OP200 exceeds 5,000,000 into a 10 k W load; input bias current is under 2 nA; CMR is over 120 dB and PSRR below 1.8 mV/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 very low, with each amplifier drawing less than 725 mA 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, MC1458/1558, and LT1013.

APPLICATIONS
DUAL LOW-POWER INSTRUMENTATION AMPLIFIER A dual instrumentation amplifier that consumes less than 33 mW of power per channel is shown in Figure 4. The linearity of the instrumentation amplifier exceeds 16 bits in gains of 5 to 200 and is better than 14 bits in gains from 200 to 1000. CMRR is above 115 dB (Gain = 1000). Offset voltage drift is typically 0.2 mV/∞C over the military temperature range which is compa- rable to the best monolithic instrumentation amplifiers. The bandwidth of the low-power instrumentation amplifier is a func- tion of gain and is shown below: TIME Minutes SHORT-CIRCUIT CURRENT mA TA = 25/H11543C VS = /H1155015V SOURCING SINKING 01 345 TPC 20.
