MAX187BEWE+T

Analog To Digital Converters (ADC) Overview

The MAX187BEWE+T 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 BE suffix indicates an extended temperature range of -40°C to +85°C. Power consumption is 7.5mW in operating mode and reduces to 10µA in shutdown.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-bit resolution with ±½ LSB integral nonlinearity for high accuracy.
• Internal track/hold circuitry supporting a 75kHz sampling rate.
• Single +5V operation with ultra-low power consumption and 2µA shutdown current.
• On-chip buffered 4.096V reference voltage source.

Analog To Digital Converters (ADC) Applications

• Portable data logging systems
• Remote digital signal processing
• Isolated data acquisition circuits
• High-accuracy process control

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the required extended temperature grade (-40°C to +85°C). Ensure the package type corresponds to the Wide SO-16 configuration specified for this part number. Check for RoHS compliance documentation as indicated by the '+' suffix.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX187 variant if an internal buffered reference is desired; otherwise, use the MAX189 for external reference requirements. Ensure the system supports the 3-wire serial interface timing constraints. Verify that the analog input impedance allows for the specified 1.5µs acquisition time. Consider the shutdown pin functionality for power management strategies in battery-operated designs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX187/MAX189 family of low-power serial ADCs. It shares architectural similarities with other Maxim Integrated data converters but is distinct in its specific combination of 12-bit resolution, single-supply operation, and integrated reference buffer. The BEWE+T designation specifies the extended temperature grade, Wide SO package, and tape-and-reel packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

MAX187CEWE+T is a direct replacement within the same family offering identical specifications but with a commercial temperature range (0°C to +70°C).
