Description
The CD8031, CD8032, CD8034, families of products offer low voltage operation and rail-to-rail input and output, as well as excellent speed/power consumption ratio, providing an excellent bandwidth (15kHz) and slew rate of 7.5V/ms. The op-amps are unity gain stable and feature an ultra-low input bias current. The devices are ideal for sensor interfaces, active filters and portable applications.
The CD8031, CD8032, CD8034 families of operational amplifiers are specified at the full temperature range of −40°C to +125°C under single or dual power supplies of 1.4V to 5.5V.
