MAX186BEWP+T

ADCs/DACs - Special Purpose Overview

The MAX186BEWP+T is a low-power, 8-channel, serial 12-bit analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuitry, and a successive-approximation register (SAR) architecture. The device operates on a single +5V or dual ±5V supply, consuming 1.5mA in operating mode and under 10µA when powered down between conversions. It features an internal 4.096V reference, software-configurable unipolar/bipolar and single-ended/differential inputs, and a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The part is housed in a 20-pin shrink small-outline package (SSOP).

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution with 133ksps sampling rate and 1.5µs acquisition time.
• Integrated 8-channel multiplexer supporting single-ended or differential input configurations.
• Internal 4.096V reference voltage with programmable gain buffer amplifier.
• Ultra-low power consumption: 1.5mA active, 2µA full power-down, and <10µA quick turn-on mode.

ADCs/DACs - Special Purpose Applications

• Portable data logging systems
• High-accuracy process control instrumentation
• Automatic testing equipment
• Battery-powered medical instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'E' suffix indicates the extended temperature range of -40°C to +85°C. Confirm the '+T' suffix corresponds to tape-and-reel packaging as specified in the ordering information. Ensure the component grade matches the required accuracy specifications for the application.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring multi-channel signal acquisition with minimal power draw. The internal clock mode allows conversion speeds independent of the host processor's serial clock rate. Differential input modes require stable return-side signals within ±0.5LSB relative to AGND during conversion.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX186/MAX188 family of low-power serial ADCs. The MAX186 variant includes an internal reference, whereas the MAX188 requires an external reference. The BEWP+T designation specifies the B-grade accuracy, extended temperature range, SOIC/SSOP package type, and reel packaging format.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX186CCAP+ serves as a functional substitute within the same family, offering identical electrical characteristics but restricted to the commercial temperature range of 0°C to +70°C. Verify package compatibility and temperature requirements before substitution.
