Overview
The MAX147BCPP is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX146/MAX147 family, which combines an 8-channel multiplexer, high-bandwidth track/hold, and a serial interface. The MAX147BCPP operates from a single +2.7V to +5.25V supply, making it versatile for various applications. It supports both unipolar and bipolar, as well as single-ended and differential analog input configurations, which are software configurable. The device features a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE, and it can perform successive-approximation analog-to-digital conversions using either an internal or external clock.
