MAX187ACPA

Analog To Digital Converters (ADC) Overview

The MAX187ACPA+ is a single-channel, 12-bit successive-approximation analog-to-digital converter (ADC) operating from a single +5V supply. It features an internal track/hold circuit and achieves a throughput rate of 75ksps with an 8.5µs conversion time. The device utilizes a high-speed 3-wire serial interface compatible with SPI, QSPI, and Microwire standards. Key electrical specifications include ±0.5 LSB integral nonlinearity, ±1 LSB differential nonlinearity, and a typical operating current of 1.5mA. Power consumption reduces to 10µA in shutdown mode. The component is housed in an 8-pin PDIP package and operates within a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ACPA+' against the manufacturer's official ordering guide to confirm the temperature grade and lead-free status. Ensure the selected variant matches the required operational environment. Cross-reference the datasheet revision date to validate that all electrical characteristics align with current production standards before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX187ACPA+ when an integrated voltage reference is required to minimize external component count. Choose this part over the MAX189 if system design constraints favor a single-supply operation with an internal 4.096V reference. Verify that the 75ksps sampling rate and 12-bit resolution meet the dynamic performance requirements of the target application.

Analog To Digital Converters (ADC) Part Context

The MAX187ACPA+ belongs to the MAX187/MAX189 family of low-power, 12-bit serial ADCs manufactured by Analog Devices / Maxim Integrated. This series is designed for applications requiring high accuracy and minimal power consumption in small form factors. The 'A' designation indicates specific linearity grades, while 'C' denotes the commercial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations
