MAX187CCPA+

Analog To Digital Converters (ADC) Overview

The MAX187CCPA+ is a +5V, low-power, 12-bit serial analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and accepts a 0 to 5V analog input. The device features an 8.5µs successive-approximation ADC, a fast track/hold with 1.5µs acquisition time, an on-chip clock, and a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE. It digitizes signals at a 75ksps throughput rate. The MAX187 includes an internal buffered reference and consumes only 7.5mW in normal operation, reducing to 10µA in shutdown. It is housed in an 8-pin PDIP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component against official datasheets for pinout, electrical characteristics, and packaging details. Confirm that the ordering suffix matches the required temperature range and reference configuration. Ensure compatibility with system voltage levels and serial interface protocols before integration.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX187CCPA+ when a 12-bit resolution and 75ksps sampling rate are required in a low-power, single-supply application. The internal buffered reference simplifies design compared to external reference solutions. Consider the 8-pin PDIP package for through-hole mounting requirements and verify that the 3-wire serial interface aligns with the host microcontroller's communication capabilities.

Analog To Digital Converters (ADC) Part Context

The MAX187/MAX189 series consists of +5V, low-power, 12-bit serial ADCs. The MAX187 variant integrates an internal buffered reference, while the MAX189 requires an external reference. Both devices share similar performance characteristics, including a 75ksps throughput rate and a 3-wire serial interface. They are designed for applications where power consumption and space are critical constraints.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the MAX187 family include other temperature grades or package variants such as MAX187CEWE+. Verify that any replacement maintains the same 12-bit resolution, 75ksps throughput, and serial interface compatibility.
