MAX181ACPL

ADCs/DACs - Special Purpose Overview

The MAX181ACPL is a complete 12-bit 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 successive approximation analog-to-digital converter (ADC) with a serial interface. The device operates with a single +5V supply or dual ±5V supplies. Key electrical parameters include a maximum conversion time of 10 µs, corresponding to a sampling rate of 100 ksps. The analog input voltage range spans from -2.5 V to +2.5 V. The unit is housed in a 40-pin Plastic DIP package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-channel multiplexer with software-configurable unipolar/bipolar and single-ended/differential inputs
• High-bandwidth track-and-hold amplifier supporting up to 100 ksps sampling rate
• Serial interface compatible with SPI, QSPI, and MICROWIRE standards without external logic
• Operates on single +5V or dual ±5V power supplies

ADCs/DACs - Special Purpose Applications

• Industrial process control systems requiring multi-channel signal conditioning
• Data acquisition modules for monitoring environmental or mechanical sensors
• Portable instrumentation utilizing low-power ADC architectures
• Battery-powered test equipment needing efficient power management

ADCs/DACs - Special Purpose Part Context

The MAX181ACPL belongs to the MAX181/MAX188 family of low-power, serial 12-bit ADCs. This series is designed for applications demanding moderate speed and resolution with minimal external component count. The 'A' suffix typically denotes an extended industrial temperature range, while 'CPL' indicates the specific 40-pin DIP packaging configuration used for through-hole mounting.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX188, which shares similar architectural features but may differ in specific timing or supply requirements. Engineers should verify that any substitute maintains compatibility with the existing serial communication protocol and analog input voltage ranges.
