MAX11103ATB+T

Analog To Digital Converters (ADC) Overview

The MAX11103ATB+T is a 12-bit successive approximation register (SAR) analog-to-digital converter featuring a dual-channel single-ended input architecture. It operates at a throughput of 3Msps with no pipeline delay, consuming 5.2mW at full speed and 3.7mW at 2Msps. The device supports a supply voltage range of 2.2V to 3.6V and includes an external reference input. It utilizes a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The component is housed in a 10-pin TDFN package and functions reliably across a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix ATB corresponds to the 10-pin TDFN-EP package configuration. Confirm that the lead-free and RoHS-compliant status matches project requirements. Ensure the datasheet revision aligns with the manufacturing batch specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution and 3Msps sampling rate are required for dual-channel applications. The external reference input distinguishes it from single-channel variants that generate internal references. Verify that the 3-wire serial interface timing meets the host microcontroller's clock constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11102/03/05/06/10/11/15/16/17 family of low-power serial ADCs. It shares architectural similarities with other members but is specifically defined by its 12-bit resolution, 3Msps speed, and dual-channel configuration. The ATB suffix identifies the specific thermal pad package variant within this series.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11102AUB+T serves as a functional substitute offering identical pinout and features but operates at a reduced 2Msps conversion rate.
