Detailed Description
Dual operational amplifier featuring low offset voltage (20µV) and high common-mode rejection ratio (115dB). This general-purpose amplifier offers a 1MHz bandwidth and 140dB voltage gain, suitable for industrial temperature ranges (-40°C to 85°C). It operates with dual supply voltages from ±2V to ±18V, drawing 790µA per channel. The component is surface-mount in an 8-pin SOIC package with gold-plated gull-wing terminals.
