MAX187CEWE+

Analog To Digital Converters (ADC) Overview

The MAX187CEWE+ is a +5V, low-power, 12-bit serial analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features an internal track/hold circuit and operates at a throughput rate of 75ksps. The device utilizes a successive-approximation register (SAR) architecture and communicates via a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. It includes an on-chip buffered reference voltage of 4.096V. The component is housed in a 16-pin Wide SO package and supports single-ended input signals ranging from 0V to VREF.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) and 'WE' denotes the 16-pin Wide SO package. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring a single +5V supply and minimal external reference components. Ensure the host microcontroller supports the required 3-wire serial timing. Consider the MAX189 if an external reference is preferred over the internal one.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX187/MAX189 family of low-power serial ADCs. The MAX187 variant distinguishes itself by integrating an internal reference, whereas the MAX189 requires an external reference. Both share identical pinouts and performance characteristics except for the reference configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX187BEWE+ is a direct replacement offering improved accuracy specifications within the same package and electrical constraints.
