The OP470 is a high-performance monolithic quad operational amplifier with exceptionally low voltage noise and high gain, making it ideal for a wide range of applications.
The OP470 quad op‑amp from Analog Devices offers exceptionally low voltage noise (3.2 nV/√Hz at 1 kHz) and low offset voltage (0.14 mV typical, 0.4 mV max). It is unity‑gain stable, has a gain‑bandwidth product of 6 MHz, and provides high CMRR (110 dB) and PSRR performance.
The handbook includes full electrical specifications, pin‑connection diagrams for DIP and SOIC packages, ordering information, and application guidance such as noise analysis, digital panning control, and squelch amplifier circuits.
