MAX181BCPL+

ADCs/DACs - Special Purpose Overview

The MAX181BCPL+ is a complete, single-supply data acquisition system manufactured by Analog Devices Inc. (Maxim Integrated). It integrates an 8-channel multiplexer, a high-bandwidth track-and-hold amplifier, and a 12-bit successive approximation analog-to-digital converter (ADC) with a sampling rate of 100ksps. The device operates on a single +5V supply and features a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards. Packaged in a 40-pin PLCC, it supports software-configurable unipolar or bipolar input ranges.

ADCs/DACs - Special Purpose Part Context

The MAX181BCPL+ belongs to the MAX181 family of complete data acquisition systems. The 'B' suffix typically denotes a specific performance grade within the series, while 'CPL+' indicates the commercial temperature range and lead-free PLCC package. This component consolidates multiple discrete functions into a single IC to reduce board space and design complexity.

ADCs/DACs - Special Purpose Replacement Considerations

Verify pin compatibility and electrical specifications against alternatives such as the MAX181BEPL+. Ensure that the replacement part supports the required 100ksps sampling rate and single-supply operation. Check for any differences in serial interface timing requirements.
