OP11

Quad Matched 741-Type Operational Amplifiers OP11 02784-001 FEATURES Guaranteed VOS: 500 μV maximum Guaranteed matched CMRR: 94 dB minimum Guaranteed matched VOS: 750 μV maximum LM148/LM348 direct replacement Low noise Silicon-nitride passivation Internal frequency compensation Low crossover distortion Continuous short-circuit protection Low input bias current GENERAL DESCRIPTION The OP11 provides four matched 741-type operational amplifiers in a single 14-lead PDIP. The OP11 is pin compatible with the LM148, LM348, RM4156, RM4158, and HA4741 amplifiers. The amplifier is matched for common-mode rejection ratio and offset voltage, which is very important in designing instrumentation amplifiers. In addition, the amplifier is designed to have equal positive-going and negative-going slew rates, which is an important consideration for good audio system performance. The OP11 is ideal for use in designs requiring minimum space and cost while maintaining performance.
