Available in the industry standard 8-pin pinout, the OP200 combines precision performance with the space and cost savings offered by a dual amplifier. 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. – –IN B 7 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 kW load; input bias current is under 2 nA; CMR is over 120 dB and PSRR below 1.8 mV/V. On-chip zenerzap trimming is used to achieve the extremely low input offset voltage of the OP200 and eliminates the need for offset pulling. – –IN A 1 +IN A 2 + FEATURES Low Input Offset Voltage: 75 V Max Low Offset Voltage Drift, Over –55C < TA < +125C: 0.5 V/C Max Low Supply Current (Per Amplifier): 725 mA Max High Open-Loop Gain: 5000 V/mV Min Low Input Bias Current: 2 nA Max Low Noise Voltage Density: 11 nV/÷Hz at 1 kHz Stable with Large Capacitive Loads: 10 nF Typ Pin Compatible to OP221, MC1458, and LT1013 with Improved Performance Available in Die Form 9 NC NC = NO CONNECT EPOXY MINI-DIP (P-Suffix), 8-Pin Hermetic DIP (Z-Suffix) OUT A 1 –IN A 2 +IN A 3 A – + B + – V– 4 8 V+ 7 OUT B 6 –IN B 5 +IN B The OP200 is an ideal choice for applications requiring multiple precision op amps and where low power consumption is critical.

Nonetheless, good supply decoupling is highly recommended. Proper supply decoupling reduces problems caused by supply line noise and improves the capacitive load driving capability of the OP200. +15V 3 VIN 5 1/2 OP200AZ VREF 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 comparable to the best monolithic instrumentation amplifiers. The bandwidth of the low-power instrumentation amplifier is a function of gain and is shown below: Gain Bandwidth 5 10 100 1000 150 kHz 67 kHz 7.5 kHz 500 Hz 20k 1 VOUT 2 7 4 6 APPLICATIONS DUAL LOW-POWER INSTRUMENTATION AMPLIFIER 8 1/2 OP200AZ –15V 5k 5k 20k RG VOUT = 5 + 40000 VIN + VREF RG Figure 4.
