DAC0802LCM/NOPB Equivalent & Substitute Parts

Part Overview

The DAC0802LCM/NOPB is an 8-bit digital-to-analog converter manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This component functions as a multiplying DAC with current output, designed for data acquisition applications requiring parallel digital interface and external voltage reference configuration. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new production designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC0802LCM/NOPB is based on strict electrical and mechanical parameter alignment. The following criteria determine valid equivalents:

Core Compatibility Parameters:

• Resolution: 8-bit digital-to-analog conversion
• Output Configuration: Current output, unbuffered, differential
• Data Interface: Parallel digital input
• Reference Input: External voltage reference
• Architecture: Multiplying DAC topology
• Package: 16-SOIC surface mount form factor
• Voltage Supply Range (Analog): ±4.5V ~ 18V
• Mounting: Surface mount on PCB

All substitute parts listed maintain these core parameters. Variations in settling time (135µs vs. 150µs), operating temperature range, and digital supply voltage specifications do not affect functional substitution within the defined electrical envelope. Packaging format differences (tube, cut tape, tape & reel) represent logistics variations only and do not impact electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are manufactured by Analog Devices Inc. and maintain active product status, ensuring long-term availability and supply chain continuity. Each substitute part carries ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the original DAC0802LCM/NOPB component.

DAC08CSZ and DAC08CSZ-REEL support extended operating temperature range (-40°C ~ 85°C) compared to the original specification (0°C ~ 70°C), providing broader thermal operational envelope for demanding applications. These variants are available in tube and cut tape/digi-reel packaging formats respectively.

DAC08ESZ and DAC08ESZ-REEL maintain the original operating temperature specification (0°C ~ 70°C) and are available in tube and tape & reel packaging formats respectively. These variants provide direct thermal compatibility with the original design specification.

All substitute parts exhibit settling time of 150µs, which represents a 15µs increase from the original 135µs specification. This parameter difference does not affect functional substitution within standard data acquisition applications.

Frequently Asked Questions (FAQ)

Q: Can DAC08CSZ replace DAC0802LCM/NOPB in all applications?

A: DAC08CSZ maintains all core electrical parameters required for substitution: 8-bit resolution, current output, differential configuration, parallel interface, external reference, and multiplying DAC architecture. The extended operating temperature range (-40°C ~ 85°C) provides broader thermal capability than the original (0°C ~ 70°C). Settling time increases from 135µs to 150µs. Substitution is valid for applications within the original 0°C ~ 70°C thermal envelope.

Q: What is the difference between DAC08CSZ and DAC08CSZ-REEL?

A: Both parts are electrically identical. The difference is packaging format: DAC08CSZ is supplied in tube packaging, while DAC08CSZ-REEL is supplied in cut tape and digi-reel format. Selection depends on production volume and assembly line requirements.

Q: Why does DAC08ESZ have the same operating temperature as the original part?

A: DAC08ESZ is specified for 0°C ~ 70°C operation, matching the original DAC0802LCM/NOPB thermal specification. This variant provides direct thermal compatibility for designs with temperature-constrained requirements.

Q: Are all substitute parts in the same 16-SOIC package?

A: Yes. All substitute parts use the 16-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical and PCB layout compatibility with the original design.

Q: What is the significance of the 15µs settling time difference?

A: The original part specifies 135µs settling time, while all Analog Devices substitutes specify 150µs. This 15µs difference represents acceptable performance variation within standard data acquisition applications and does not constitute a functional limitation for substitution.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts carry ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment with the original component.
