OP-220

The OP-220 is a monolithic dual operational amplifier that can be used either in single or dual supply operation.The low offset voltage, and input offset voltage tracking as low as 1.0 V/, make this the first micropower precision dual operational amplifier.The excellent specifications of the individual amplifiers combined with the tight matching and temperature tracking between channels provides high performance in instrumentation amplifier designs. The individual amplifiers feature extremely low input offset voltage, low offset voltage drift,low noise voltage, and low bias current. They are fully compensated and protected.

Features of the OP-220 are:(1)excellent TCVos match:2V/ Max; (2)low input offset voltage:150V Max; (3)low supply current:100A; (4)single-supply operation:+5V to +30V; (5)low input offset voltage drift:0.75V/; (6)high open-loop gain:2000V/mV; (7)high PSRR:3V/V; (8)low input bias current :12nA; (9)wide common-mode voltage range:V- to within 1.5V of V+; (10)pin compatible with 1458, LM158, LM2904; (11)available in die form.The OP-220 offers a unique camblnatlan of excellent do performance, wide input range, and lawsupplycurrent drain that is particularly attractive far instrumentation amplifier design.

The absolute maximum ratings of the OP-220 can be summarized as:(1)supply voltage:±18V;(2)storage temperature range:-65 to +150;(3)operating temperature:-40 to 85;(4))lead temperature:300;(5)different input voltage:3V or supply voltage.The excellent input characteristics of the OP-220 make it ideal for use in instrumentation amplifier configurations where low-level differential signals are to be amplified. The low-noise, low input offsets, low drift, and high gain combined  with excellent CMRR provide the characteristics needed for high-performance instrumentation amplifiers. In addition, the power supply current drain is very low.This three-op-amp instrumentation amplifier configuration using an OP-220 at the input and an OP-22 at the output provides excellent pei"fprmance over a wide gain range with very low power consumption. A gain range of,to 2000 is practical and CMR of over 120dB is headily achievable.
