CBM8221 Low cost, low power consumption, low noise, single channel operational amplifier

The CBM8221, CBM8222, CBM8224, CBM8221S, CBM8222S 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 (500kHz) and slew rate of 0.18V/us. 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 CBM8221S, CBM8222S include a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is less than 1uA.The CBM8221, CBM8222, CBM8224, CBM8221S, CBM8222S families of operational amplifiers are specified at the full temperature range of −40°C to +125°C under single or dual power supplies of 2.5V to 5.5V.
