CA5260E

Instrumentation, Op Amps, Buffer Amps Overview

The CA5260E is a dual BiMOS microprocessor operational amplifier featuring MOSFET input and CMOS output stages. It operates on single +5V supplies or split rails from ±2.25V to ±8V. The device offers a 3MHz bandwidth, 1.5TΩ typical input impedance, and 5pA typical input bias current at 15V. Output voltage swings within 10mV of supply rails. It supports common-mode input voltages down to 0.5V below the negative rail and functions reliably across the -55°C to 125°C military temperature range.
