DAC0802LCMX Equivalent & Substitute Parts

Part Overview

The DAC0802LCMX is an 8-bit digital-to-analog converter manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This device functions as a multiplying DAC with current output, designed for data acquisition applications requiring parallel digital interface and external voltage reference configuration. The DAC0802LCMX carries a "Not For New Designs" status, making identification of functionally equivalent alternatives necessary for ongoing production and design updates. Substitute parts must maintain identical electrical specifications and mechanical compatibility while offering active product status where available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC0802LCMX is determined by strict alignment of core electrical and mechanical parameters. All substitute parts must maintain the following critical specifications:

• 8-bit resolution with single D/A converter configuration
• Current output, unbuffered topology with differential output capability
• Parallel digital interface with external reference requirement
• Multiplying DAC architecture
• ±4.5V to 18V analog supply voltage range
• 16-SOIC surface mount package with identical 0.154" (3.90mm) width
• ROHS3 compliance and MSL 1 rating

Settling time variations (135µs vs. 150µs) and operating temperature ranges do not preclude substitution when application requirements are met. Packaging format differences (Tape & Reel, Cut Tape, Tube) represent logistics variations only and do not affect electrical compatibility. Product status transitions from "Not For New Designs" to "Active" indicate improved availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

DAC0802LCMX/NOPB represents the direct Texas Instruments equivalent with active product status, maintaining identical electrical specifications and settling time while offering improved lifecycle support compared to the original DAC0802LCMX. This part is the preferred choice for applications requiring Texas Instruments sourcing continuity.

Analog Devices DAC08 series parts (DAC08CSZ, DAC08CSZ-REEL, DAC08ESZ, DAC08ESZ-REEL) provide cross-manufacturer substitution with full electrical compatibility. All DAC08 variants carry active product status and ROHS3 compliance. Selection among DAC08 options depends on packaging requirements and operating temperature specifications:

DAC08CSZ and DAC08ESZ differ only in operating temperature range (-40°C to 85°C versus 0°C to 70°C) and packaging format (Tube versus Tube). DAC08CSZ-REEL and DAC08ESZ-REEL provide tape and reel packaging variants with identical temperature specifications to their non-reeled counterparts.

Applications operating within 0°C to 70°C temperature limits may use DAC08ESZ or DAC08ESZ-REEL. Applications requiring extended temperature operation to -40°C must use DAC08CSZ or DAC08CSZ-REEL. High-volume production requiring tape and reel format should specify DAC08ESZ-REEL or DAC08CSZ-REEL accordingly.

Frequently Asked Questions (FAQ)

Q: Can DAC08 series parts from Analog Devices directly replace DAC0802LCMX in existing designs?

A: Yes. All DAC08 variants maintain identical 8-bit resolution, current output topology, differential output capability, parallel interface, external reference requirement, multiplying DAC architecture, and 16-SOIC surface mount package. Electrical specifications align within specified parameters.

Q: What is the significance of the settling time difference between DAC0802LCMX (135µs) and DAC08 series (150µs)?

A: Settling time represents the interval required for output current to stabilize following a digital input change. The 15µs difference does not preclude substitution; applications must confirm that 150µs settling time meets timing requirements. Designs with critical settling time constraints should evaluate this parameter against application specifications.

Q: How do packaging format differences affect substitution?

A: Packaging format (Tape & Reel, Cut Tape, Tube) represents logistics and handling variation only. Electrical and mechanical compatibility remain unchanged. Selection should align with assembly process requirements and inventory management practices.

Q: Why do DAC08CSZ and DAC08ESZ carry different operating temperature ranges?

A: DAC08CSZ operates from -40°C to 85°C, while DAC08ESZ operates from 0°C to 70°C. Applications requiring extended low-temperature operation must specify DAC08CSZ. Applications within 0°C to 70°C may use either variant.

Q: Is DAC0802LCMX/NOPB functionally identical to DAC0802LCMX?

A: Yes. DAC0802LCMX/NOPB maintains identical electrical specifications, settling time, and package configuration. The primary difference is active product status versus "Not For New Designs" designation, indicating ongoing manufacturer support and availability.

Q: What does "Not For New Designs" status mean for the original DAC0802LCMX?

A: This designation indicates the part is in end-of-life phase and not recommended for new product development. Existing designs may continue using available inventory, but new designs should transition to active alternatives such as DAC0802LCMX/NOPB or DAC08 series parts.
