MAX11612EUA+T

MAX11612EUA+T is a low-power, 12bit, multichannel analogue-to-digital converter (ADC). It features internal track/hold (T/H), voltage reference, clock, and an I²C-compatible 2-wire serial interface. Supply current falls below 230µA for sampling rates under 40ksps. Auto Shutdown™ powers down the devices between conversions, reducing supply current to less than 1µA at low throughput rates. This device have 4 analogue input channels. The fully differential analogue inputs are software configurable for unipolar or bipolar, and single-ended or differential operation. The full-scale analogue input range is determined by the internal reference or by an externally applied reference voltage ranging from 1V to VDD. It is used in applications such as handheld portable applications, medical instruments, battery-powered test equipment, solar-powered remote systems, received-signal-strength indicators, system supervision.
