MAX1329BETL+

Specialized ICS Overview

The MAX1329BETL+T is a smart data acquisition system (DAS) integrating a successive approximation register (SAR) analog-to-digital converter (ADC), digital-to-analog converters (DACs), operational amplifiers, voltage reference, temperature sensors, and analog switches. The ADC operates in normal mode at up to 12 bits resolution and 312ksps, or in DSP mode at 16 bits and 1000sps. It features a programmable gain amplifier (PGA) with gains of 1V/V to 8V/V, dual 12-bit force-sense DACs, and four analog/digital programmable I/Os. The device runs on a 1.8V to 3.6V digital supply with an internal charge pump for analog circuits.

Specialized ICS Procurement Notes

Verify the ordering suffix +T indicates reel packaging when sourcing. Confirm the BE suffix corresponds to the -40°C to +85°C operating temperature range. Ensure the component is lead-free and RoHS-compliant as indicated by the plus sign in the part number.

Specialized ICS Selection Notes

Select the MAX1329 variant specifically for its dual 12-bit force-sense DAC configuration. Consider the MAX1330 if two op amps are required instead of dual DACs. Verify that the 40-TQFN package dimensions fit the PCB layout constraints.

Specialized ICS Part Context

This component belongs to the MAX1329/MAX1330 family of smart data acquisition systems. These devices combine high-performance analog conversion capabilities with digital control features in a single integrated circuit, designed for applications requiring compact form factors and low power consumption.
