MAX1247BEEE

MAX1247BEEE Description

The MAX1247BEEE is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices Inc./Maxim Integrated, designed for precision data acquisition in low-power embedded systems. Housed in a 16-QSOP package, it features a single ADC with SPI-compatible serial interface, supporting both single-ended and differential inputs (configurable as 2 or 4 channels). Operating from 2.7V to 5.25V (analog/digital supplies), it delivers a 133k samples/sec throughput with a 1:1 sample-and-hold (S/H) to ADC ratio, ensuring minimal latency. The device requires an external reference and is optimized for applications demanding high accuracy in compact form factors.
