This document provides technical specifications for the OP-270 (dual) and OP-470 (quad) operational amplifiers from Linear Technology. These devices are designed as high-performance alternatives to industry standards like the OP-27, offering very low input noise of 80nVp-p and input offset voltages below 75µV for the dual version.
The datasheet details electrical characteristics including gain bandwidth product (6MHz typical), slew rate (3.0V/µs), and common mode rejection ratio (minimum 106dB). It covers absolute maximum ratings, supply current consumption, and provides part ordering information for various package types such as 8-lead ceramic DIP and plastic DIP.
| Input Noise Voltage Density (1kHz) | 3.2nV/√Hz Typ |
|---|---|
| Gain Bandwidth Product | 6MHz Typ |
| Slew Rate | 3.0V/µs Typ |
They are suitable for instrumentation amplifiers, low noise signal processing, microvolt accuracy threshold detection, and strain gauge accelerometers.
The power consumption of the dual OP-270 is one-third less than two standard OP-27s.
