MAX11666AUB+T

Analog To Digital Converters (ADC) Overview

The MAX11666AUB+T is a 12-bit, 500ksps successive-approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It features two single-ended analog inputs and operates on a 2.2V to 3.6V supply with 3.3mW power consumption. The device utilizes an external reference input and communicates via a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Packaged in a 10-pin µMAX format, it supports variable I/O levels from 1.5V to 3.6V for direct connection to various digital systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through authorized distributors or manufacturer channels. Confirm the package type matches the 10-pin µMAX specification and ensure the operating temperature range meets the -40°C to +125°C requirement for the intended application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model when dual-channel acquisition is required with 12-bit precision. Ensure the system design accommodates an external reference voltage between 1V and VDD. Verify that the host microcontroller supports the 3-wire serial interface timing requirements for optimal data throughput.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX11661–MAX11666 family of low-power ADCs. While other variants in the series offer different resolutions (8-bit, 10-bit) or channel counts (single-ended), the MAX11666 specifically provides 12-bit resolution with dual analog inputs, distinguishing it from single-channel counterparts like the MAX11665.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX11664 (10-bit) or MAX11662 (8-bit). For higher resolution requirements, consider the MAX11166, though it requires interface adjustments due to its single-channel architecture and different package options.
