RC4156/RC4157
High Performance Quad Operational Amplifiers
Features
• Unity gain bandwidth for RC4156 – 3.5 MHz
• Unity gain bandwidth for RC4157 – 19 MHz
• High slew rate for RC4156 – 1.6 V/µS
• High slew rate for RC4157 – 8.0V/µS
• Low noise voltage – 1.4 µVRMS
• Indefinite short circuit protection
• No crossover distortion
Description
The RC4156 and RC4157 are monolithic integrated circuits,
consisting of four independent high performance operational
amplifiers constructed with an advanced epitaxial process.
These amplifiers feature improved AC performance which
far exceeds that of the 741 type amplifiers. Also featured are
excellent input characteristics and low noise, making this
device the optimum choice for audio, active filter and instru-
mentation applications. The RC4157 is a decompensated
version of the RC4156 and is AC stable in gain configura-
tions of -5 or greater.
