DAC82002DRXR Equivalent & Substitute Parts

Part Overview

The DAC82002DRXR is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for precision voltage output applications in data acquisition systems. This single-channel DAC operates with external reference voltage and features a 3-wire serial SPI interface, making it suitable for embedded systems requiring high-resolution analog signal generation. The device is classified as Active product status with full RoHS3 compliance and Moisture Sensitivity Level 2 rating.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent functional performance across identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC82002DRXR is determined by strict equivalence across the following critical parameters:

Resolution & Conversion Characteristics: 16-bit resolution with 1 D/A converter channel and 1µs typical settling time establish the functional baseline for signal conversion accuracy and speed.

Electrical Interface Specifications: 3-wire serial SPI data interface, external voltage reference architecture, and dual supply voltage range (2.7V ~ 5.5V for both analog and digital supplies) define the system integration requirements.

Precision Metrics: INL/DNL specifications of ±0.6 LSB and ±0.5 LSB respectively establish the linearity and monotonicity performance envelope.

Physical & Environmental Compliance: 10-WSON (2.5x2.5) package footprint, surface mount configuration, RoHS3 compliance, and MSL 2 rating ensure mechanical and environmental compatibility.

The DAC82001DRXR qualifies as a parametric equivalent substitute based on identical electrical specifications, identical package geometry, and matching compliance certifications across all specified parameters.
