Maxim Integrated MAX1396EUB

Description
The MAX1393/MAX1396 are micropower, serial-output, 12-bit analog-to-digital converters (ADCs) that operate with a single power supply from 1.5V to 3.6V. These ADCs feature automatic shutdown, fast wake-up, and a high-speed 3-wire interface. Power consumption is only 0.734mW (VDD = 1.5V) at the maximum conversion rate of 312.5ksps. AutoShutdown™ between conversions reduces power consumption at slower throughput rates.
The MAX1393/MAX1396 require an external reference VREF that has a wide range from 0.6V to VDD. The MAX1393 provides one true-differential analog input that accepts signals ranging from 0 to VREF (unipolar mode) or ±VREF/2 (bipolar mode). The MAX1396 provides two single-ended inputs that accept signals ranging from 0 to VREF. Analog conversion results are available through a 5MHz 3-wire SPI™-/QSPI™/MICROWIRE™/digital signal processor (DSP)-compatible serial interface.
