DAC811JUG4 Equivalent & Substitute Parts

Part Overview

The DAC811JUG4 is a 12-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring voltage output buffering. This component features an R-2R architecture with internal reference, parallel data interface, and operates across dual supply voltages (±11.4V to ±16.5V analog, 5V digital). The DAC811JUG4 is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain design continuity and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitution of the DAC811JUG4 is determined by strict equivalence across the following critical parameters: 12-bit resolution, single D/A converter configuration, 4µs settling time, buffered voltage output, parallel data interface, internal reference architecture, dual supply voltage range (±11.4V to ±16.5V analog, 5V digital), INL/DNL specifications (±0.25, ±0.5 LSB), R-2R architecture, 28-SOIC package footprint, and surface mount compatibility. The DAC811JU qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between the main part and substitute is product status and packaging format, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DAC811JU is the direct equivalent substitute for the DAC811JUG4. Both components share identical electrical specifications, package footprint, and compliance certifications (ROHS3, REACH Unaffected). The DAC811JU maintains active product status with higher inventory availability (2578 units in stock versus 1403 units for the discontinued DAC811JUG4), ensuring supply chain continuity. The DAC811JU is supplied in tube packaging, which is standard for production environments. No electrical or mechanical redesign is required when substituting the DAC811JU for the DAC811JUG4 in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the DAC811JU be used as a direct replacement for the DAC811JUG4? A: Yes. Both parts are electrically and mechanically identical, with matching 12-bit resolution, 4µs settling time, buffered voltage output, parallel interface, internal reference, dual supply voltage requirements, and 28-SOIC package configuration.

Q: What is the difference between DAC811JUG4 and DAC811JU? A: The primary difference is product status and packaging. The DAC811JUG4 is discontinued at DiGi Electronics, while the DAC811JU is active. The DAC811JU is supplied in tube packaging. All electrical and functional specifications are identical.

Q: Are there any PCB layout or schematic modifications required when switching to the DAC811JU? A: No modifications are required. The 28-SOIC package footprint, pin configuration, supply voltage requirements, and signal interface are identical between both parts.

Q: What is the inventory status of the DAC811JU? A: The DAC811JU has 2578 units in stock as new original inventory, providing adequate supply for production applications.

Q: Do both parts meet the same compliance standards? A: Yes. Both the DAC811JUG4 and DAC811JU are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.
