DAC7611PG4 Equivalent & Substitute Parts

Part Overview

The DAC7611PG4 is a 12-bit digital-to-analog converter manufactured by Texas Instruments, housed in an 8-DIP package for through-hole mounting. This component provides voltage-buffered output with SPI interface and internal reference, operating across the -40°C to 85°C temperature range. The DAC7611PG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC7611PG4 are identified based on the following critical parameters that determine functional equivalence:

Core Compatibility Criteria:

• 12-bit resolution
• Single D/A converter
• Voltage-buffered output
• SPI data interface support
• Internal reference configuration
• 8-DIP through-hole package
• R-2R architecture
• -40°C to 85°C operating temperature range
• ROHS3 compliance

The substitute parts are grouped into two categories based on supply voltage specifications and product status:

Category 1 - Direct Pin-Compatible Substitutes (5V Supply): DAC7611P and DAC8512FPZ maintain identical analog and digital supply voltage requirements (5V), ensuring direct compatibility with existing 5V system designs.

Category 2 - Flexible Supply Voltage Substitutes (2.7V-5.5V Supply): AD8300ANZ provides extended supply voltage range compatibility, supporting both 5V legacy systems and lower-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in 5V Systems: DAC7611P is the primary substitute for the discontinued DAC7611PG4. Both parts share identical electrical specifications, settling time, and linearity characteristics. DAC7611P maintains the same 5V supply requirements and R-2R architecture. However, DAC7611P carries a "Not For New Designs" status, making it suitable only for legacy system maintenance and repair applications.

For New Designs and Long-Term Availability: AD8300ANZ is recommended for new production designs. This Analog Devices component maintains full functional equivalence with active product status, ensuring long-term availability and supply chain stability. The extended supply voltage range (2.7V-5.5V) provides design flexibility for future applications. Settling time increases to 14µs, which remains acceptable for most data acquisition applications.

Alternative with Extended Supply Range: DAC8512FPZ offers another active substitute with identical 5V supply specifications. This part features DSP interface capability in addition to SPI, providing additional interface flexibility. The INL/DNL specification is ±0.75 LSB compared to ±0.5 LSB for the original part, and settling time extends to 16µs. This part is suitable for applications where the relaxed linearity specification is acceptable.

Compliance and Regulatory Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original DAC7611PG4 regulatory profile. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Frequently Asked Questions (FAQ)

Q: Can DAC7611P be used as a direct replacement for DAC7611PG4? A: Yes. DAC7611P provides identical electrical performance, package configuration, and supply voltage specifications. Both are 12-bit, single-channel DACs in 8-DIP packages with SPI interface and internal reference. The primary difference is product status; DAC7611P is designated "Not For New Designs," limiting its use to legacy system support.

Q: What is the key difference between AD8300ANZ and the original DAC7611PG4? A: AD8300ANZ maintains all core functional specifications but extends the supply voltage range to 2.7V-5.5V, compared to the fixed 5V requirement of DAC7611PG4. Settling time increases from 7µs to 14µs. AD8300ANZ carries active product status, ensuring continued availability.

Q: Is DAC8512FPZ compatible with DAC7611PG4 designs? A: DAC8512FPZ is mechanically and electrically compatible in 5V systems. Both parts share identical package, resolution, and supply voltage specifications. However, DAC8512FPZ has relaxed linearity specifications (±0.75 LSB versus ±0.5 LSB) and longer settling time (16µs versus 7µs). Verify that your application tolerates these performance differences before substitution.

Q: Are all substitute parts available in the same packaging? A: Yes. All substitute parts are supplied in 8-DIP through-hole packages with identical physical dimensions (0.300", 7.62mm). All are ROHS3 compliant and suitable for standard PCB assembly processes.

Q: Which substitute should I select for a new product design? A: AD8300ANZ is the recommended choice for new designs due to active product status and extended supply voltage range. If your design requires the fastest settling time and tightest linearity specifications, AD8300ANZ provides the best balance of performance and long-term availability.

Q: Do the substitute parts support the same data interfaces? A: All substitute parts support SPI interface. AD8300ANZ and DAC8512FPZ additionally support DSP interface, providing expanded interface options. Existing SPI-based designs require no interface modifications.
