MAX188BCWP+

ADCs/DACs - Special Purpose Overview

The MAX188BCWP+ is a low-power, 8-channel, serial 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuitry, and a successive-approximation ADC core. The device operates on a single +5V or dual ±5V supply and features a software-configurable unipolar/bipolar input range with differential or single-ended modes. It utilizes a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Key electrical specifications include a 133kS/s sampling rate, 1.5mA operating current, and a maximum power dissipation of 800mW in the SO package.

• 12-bit resolution with 133kHz sampling rate and internal track/hold
• Software-selectable unipolar or bipolar input configurations
• 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE

ADCs/DACs - Special Purpose Applications

• Portable data logging systems
• Data-acquisition applications
• High-accuracy process control
• Automatic testing equipment
• Battery-powered instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify that the component is the lead-free/RoHS-compliant version indicated by the '+' suffix. Confirm the specific grade 'B' accuracy requirements against the datasheet specifications for DNL and INL. Ensure the ordering suffix matches the required temperature range and package type (SOIC-20).

ADCs/DACs - Special Purpose Selection Notes

Select the MAX188 variant over the MAX186 when an external voltage reference is required, as the MAX188 lacks an internal reference. Verify that the system can provide the necessary external reference voltage of 4.096V. Consider the 800mW power dissipation limit for the SO package when designing thermal management solutions.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX186/MAX188 family of low-power, 8-channel, serial 12-bit ADCs. The MAX188 specifically requires an external reference, distinguishing it from the internally referenced MAX186. Both share identical architecture, pinouts, and serial interface capabilities.
