MAX187BCPA

Analog To Digital Converters (ADC) Overview

The MAX187BCPA 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 a 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 1.5mA during operation, reducing to 2µA in shutdown mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCPA' against official documentation to confirm accuracy grade and package type. Ensure compatibility with existing system requirements for voltage range, sampling rate, and serial interface protocols before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX187BCPA when a 12-bit resolution with ±½ LSB INL is required alongside low power consumption. Consider the internal 4.096V reference if external components are to be minimized. Verify that the 75ksps throughput meets the application's data acquisition needs.

Analog To Digital Converters (ADC) Part Context

The MAX187BCPA belongs to the MAX187/MAX189 family of +5V, low-power, 12-bit serial ADCs. This series is designed for applications requiring high accuracy and low power in a small footprint. The MAX187 variant specifically integrates an internal buffered reference, distinguishing it from the MAX189 which requires an external reference.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacement options include other parts within the MAX187/MAX189 family or similar 12-bit serial ADCs from Analog Devices/Maxim Integrated. Verify pinout compatibility and electrical specifications such as supply voltage and interface protocol.
