MAX11644 and MAX11645: Low-Power, 1-/2-Channel, I²C, 12-Bit ADCs in Ultra-Tiny 1.9mm x 2.2mm Package
- click to enlarge
The MAX11644/MAX11645 low-power, 12-bit, 1-/2-channel analog-to-digital converters (ADCs) feature internal track/hold (T/H), voltage reference, clock, and an I2C-compatible 2-wire serial interface. These devices operate from a single supply of 2.7V to 3.6V (MAX11645) or 4.5V to 5.5V (MAX11644) and require only 6μA at a 1ksps sample rate. AutoShutdow powers down the devices between conversions, reducing supply current to less than 1μA at low throughput rates.
The MAX11644/MAX11645 are available in an ultra-tiny 1.9mm x 2.2mm WLP package and an 8-pin μMAX® package.
