MAX187CCWE

Analog To Digital Converters (ADC) Overview

The MAX187CCWE+ is a 12-bit successive-approximation analog-to-digital converter (ADC) operating from a single +5V supply. It features an internal track-and-hold circuit with a 1.5µs acquisition time and supports a throughput rate of 75ksps. The device utilizes a high-speed 3-wire serial interface compatible with SPI, QSPI, and Microwire protocols. It includes an on-chip buffered 4.096V reference voltage source. The component operates within a commercial temperature range of 0°C to +70°C and is housed in a 16-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C). Confirm the '+W' suffix corresponds to the 16-pin Wide SOIC package. Ensure the '+' suffix denotes lead-free compliance. Cross-reference the manufacturer's latest documentation for any obsolescence notices or lifecycle status changes before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single-ended input range of 0V to VREF is required without external reference components. Choose the MAX187 variant over the MAX189 if an integrated reference simplifies the design. Consider the package constraints of the 16-pin SOIC form factor against available board space. Verify that the 75ksps sampling rate meets the system bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX187/MAX189 family of low-power serial ADCs manufactured by Analog Devices/Maxim Integrated. The series provides 12-bit resolution with varying reference configurations and accuracy grades. The MAX187 distinguishes itself by integrating a buffered reference, whereas the MAX189 requires an external reference source. Both share identical core conversion architectures and interface protocols.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the MAX187CEWE+. Users should verify pin compatibility and electrical specifications against the original datasheet before implementing any replacement.
