CDV721 Low cost, low noise, rail to rail output, single channel operational amplifier-ChisynV Microelectronics (Beijing) Co., Ltd.

The CDV72X 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 (10MHz)and slew rate of 7V/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 CDV721S, CDV722S 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 CDV72X 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.
