MAX149BCAP

Analog To Digital Converters (ADC) Overview

The MAX149BCAP+ is a low-power, 8-channel, serial 10-bit analog-to-digital converter (ADC) from the MAX148/MAX149 family. It operates on a single +2.7V to +5.25V supply and supports sampling rates up to 133ksps. The device integrates an internal 2.5V reference and features software-configurable unipolar or bipolar inputs for both single-ended and differential modes. It utilizes a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The component is housed in a 20-pin SSOP package and is specified for operation within a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix includes the '+' symbol to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm the specific 'B' grade designation matches the required integral nonlinearity specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the MAX148 variant when an integrated internal reference is preferred to reduce external component count. Ensure the operating temperature range of 0°C to +70°C aligns with system constraints, as industrial variants are available for wider thermal environments.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX148/MAX149 series of low-power data acquisition systems. It shares architectural similarities with the MAX1248/MAX1249 but provides eight channels instead of four. The 'B' suffix indicates a specific accuracy grade regarding integral nonlinearity compared to the 'A' grade.
