OP227GN#PBF

OP227 is a dual-matched precision instrumentation operational amplifier which combines low offset, low noise, and high gain with excellent matching characteristics. Matching characteristics are specified with guaranteed limits on all critical parameters including VOS, VOS drift, IBIAS, and CMRR, which makes this an ideal choice for two and three-op-amp instrumentation amplifier applications. The OP-237 offers DC specifications identical to OP-227 and is decompensated for higher-speed operation at inverting gains greater than 5. Typical applications are low-level signal processing, low-noise audio amplifiers, and strain gauge amplifiers.
