DAC6574IDGSG4 Equivalent & Substitute Parts

Part Overview

The DAC6574IDGSG4 is a 10-bit digital-to-analog converter (DAC) featuring 4 independent channels with buffered voltage output. Manufactured by Texas Instruments, this component is designed for data acquisition applications requiring precision analog signal generation from digital inputs. The device operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital supplies, making it suitable for mixed-signal system integration.

The DAC6574IDGSG4 has been discontinued at DiGi Electronics. Due to this discontinuation status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC6574IDGSG4 is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 10-bit resolution with 4 independent D/A converters
• Output Configuration: Buffered voltage output with no differential output capability
• Interface Protocol: I2C digital communication interface
• Supply Voltage Compatibility: Dual supply range of 2.7V to 5.5V for both analog and digital domains
• Timing Performance: 9µs settling time
• Linearity Specifications: INL/DNL of ±0.5 LSB and ±0.1 LSB respectively
• Thermal Range: Operating temperature from -40°C to 105°C
• Package Compatibility: 10-VSSOP surface mount package with 0.118" (3.00mm) width
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The DAC6574IDGS variant meets all these criteria and is classified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The DAC6574IDGS is the direct substitute for the discontinued DAC6574IDGSG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, thermal performance, and regulatory compliance status. The primary distinction is product availability: the DAC6574IDGSG4 is discontinued, while the DAC6574IDGS maintains active production status with confirmed inventory availability.

From a compliance perspective, both parts meet ROHS3 requirements and are REACH unaffected, ensuring regulatory alignment for new designs and production continuity. The packaging difference (Tube for the substitute versus unspecified for the main part) does not affect functional compatibility or PCB integration.

Selection of the DAC6574IDGS is appropriate for all applications previously designed around the DAC6574IDGSG4, with no circuit modifications or re-qualification required.

Frequently Asked Questions (FAQ)

Q: Are the DAC6574IDGSG4 and DAC6574IDGS electrically identical?

A: Yes. Both parts share identical electrical specifications including 10-bit resolution, 4-channel configuration, I2C interface, 9µs settling time, and supply voltage ranges of 2.7V to 5.5V. Linearity performance (INL/DNL) and operating temperature ranges are also identical.

Q: Can the DAC6574IDGS be used as a direct replacement without circuit modifications?

A: Yes. The DAC6574IDGS is a direct substitute. Both parts use the 10-VSSOP surface mount package with identical pinout and electrical characteristics. No PCB layout changes or firmware modifications are required.

Q: What is the difference between the two part numbers?

A: The primary difference is product status and packaging specification. The DAC6574IDGSG4 is discontinued at DiGi Electronics, while the DAC6574IDGS is in active production. The substitute is supplied in Tube packaging. All functional and electrical parameters remain unchanged.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 2, 1 Year) is also consistent across both variants.

Q: What inventory considerations should be evaluated?

A: The DAC6574IDGS has confirmed active inventory availability (1259 Pcs reported in stock), whereas the DAC6574IDGSG4 is discontinued. For new procurement and production planning, the DAC6574IDGS should be specified to ensure supply chain continuity.
