AD7091R-5BCPZ-RL7

AD7091R-5BCPZ-RL7 is a 12bit, ultra-low power, successive approximation analogue-to-digital converter (ADC). It operates from a single 2.7V to 5.25V power supply and typically consumes only 24µA at a 3V supply in fast mode. 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 offers four single-ended analogue input channels with a channel sequencer that allows a pre-programmed selection of channels to be converted sequentially. It uses advanced design techniques to achieve ultra-low power dissipation without compromising performance. 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, and diagnostic/monitoring functions.
