DAC7571IDBVRG4 Equivalent & Substitute Parts

Part Overview

The DAC7571IDBVRG4 is a 12-bit digital-to-analog converter manufactured by Texas Instruments, housed in a SOT-23-6 surface mount package. This component features a single voltage-buffered output, I2C data interface, and operates across a 2.7V to 5.5V supply range. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC7571IDBVRG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• 12-bit resolution
• Single D/A converter
• Voltage-buffered output
• I2C data interface
• SOT-23-6 package
• Supply voltage range: 2.7V ~ 5.5V (both analog and digital)
• String DAC architecture
• Surface mount configuration
• ROHS3 compliance

Substitute parts are grouped into two categories:

Category 1: Texas Instruments DAC7571 Series — Direct manufacturer equivalents with identical electrical specifications and packaging. These parts differ only in tape format (Cut Tape & Digi-Reel versus Tape & Reel).

Category 2: Microchip MCP4725 Series — Parametric equivalents offering compatible core functionality with minor performance variations. These parts maintain identical resolution, interface, package, and supply voltage specifications but feature improved settling time (6µs typical versus 10µs) and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments DAC7571IDBVR and DAC7571IDBVT are the primary substitutes for the discontinued DAC7571IDBVRG4. Both parts maintain active product status and are manufactured by the original supplier. These components are electrically and functionally identical to the original part, differing only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Selection between these two depends on procurement and assembly requirements. Both are ROHS3 compliant with MSL 1 rating.

Microchip MCP4725 Series (MCP4725A0T-E/CH, MCP4725A1T-E/CH, MCP4725A2T-E/CH, MCP4725A3T-E/CH) provide parametric equivalence with enhanced performance characteristics. These parts offer faster settling time (6µs typical versus 10µs) and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 105°C). The MCP4725 variants differ in I2C address configuration, allowing multiple devices on a single bus. All MCP4725 parts are active, ROHS3 compliant, and carry MSL 1 rating. Selection among MCP4725 variants depends on I2C address requirements for the application.

For applications requiring strict electrical equivalence with the original DAC7571IDBVRG4, the Texas Instruments DAC7571 alternatives are recommended. For applications where improved settling time and extended temperature range provide design benefits, the Microchip MCP4725 series offers compatible substitution.

Frequently Asked Questions (FAQ)

Q: Can DAC7571IDBVR or DAC7571IDBVT be used as direct replacements for DAC7571IDBVRG4?

A: Yes. Both parts are electrically and functionally identical to the original DAC7571IDBVRG4. The differences are limited to packaging format (Cut Tape & Digi-Reel versus Tape & Reel). No circuit modifications are required for substitution.

Q: What is the difference between the MCP4725 variants (A0, A1, A2, A3)?

A: The MCP4725 variants differ in I2C slave address configuration. The address suffix (A0, A1, A2, A3) designates the I2C address, enabling multiple MCP4725 devices to operate on the same I2C bus. Electrical performance and package specifications are identical across all variants.

Q: Are MCP4725 parts compatible with DAC7571IDBVRG4 applications?

A: MCP4725 parts are parametrically compatible with DAC7571IDBVRG4. Both feature 12-bit resolution, I2C interface, SOT-23-6 packaging, and identical supply voltage ranges. MCP4725 parts offer improved settling time (6µs typical) and extended operating temperature range (-40°C ~ 125°C). No PCB layout changes are required due to identical package specifications.

Q: What are the key differences between DAC7571 and MCP4725 series?

A: The primary differences are settling time and operating temperature range. DAC7571 parts settle in 10µs across -40°C ~ 105°C. MCP4725 parts settle in 6µs (typical) across -40°C ~ 125°C. INL/DNL specifications differ slightly: DAC7571 specifies ±1 LSB maximum, while MCP4725 specifies ±2 and ±0.2 LSB. All other electrical and mechanical parameters are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (DAC7571IDBVR, DAC7571IDBVT, and all MCP4725 variants) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I mix DAC7571 and MCP4725 parts in the same production run?

A: Yes, provided the application tolerates the parameter differences noted in the comparison table. Identical SOT-23-6 packaging and I2C interface enable interchangeability at the PCB level. Firmware or application-level considerations regarding settling time and temperature range should be evaluated.
