AD7091R-5BRUZ-RL7

AD7091R-5BRUZ-RL7 is a 12bit, multichannel, ultra low power, successive approximation analogue-to-digital converter (ADC). It provides a 2-wire serial interface compatible with I²C interfaces. The conversion process can be controlled by a sample mode via the CONVST/GPO1 pin, an autocycle mode selected through software control, or a command mode in which conversions occur across I²C write operations. This device contains a wide bandwidth track-and-hold amplifier that can handle input frequencies upto 1.5MHz. It also features an on-chip conversion clock, an on-chip accurate 2.5V reference, and a programmable out of bounds user alert function. It is used in applications such as battery-powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, data acquisition systems, optical sensors, diagnostic/monitoring functions.
