Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC6573IPWG4 is determined by strict equivalence across the following critical parameters:

• Resolution: 10-bit
• Channel Count: 4 independent D/A converters
• Output Configuration: Voltage output with buffering
• Control Interface: I2C protocol
• Reference Input: External reference capability
• Supply Voltage Ranges: 2.7V to 5.5V (both analog and digital)
• Linearity Specifications: INL/DNL of ±0.5 LSB and ±0.1 LSB
• Package Type: 16-TSSOP form factor
• Thermal Range: -40°C to 105°C operation

The DAC6573IPW qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The DAC6573IPW is the recommended substitute for the discontinued DAC6573IPWG4. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters including resolution, channel configuration, settling time, supply voltage ranges, and linearity performance.

The DAC6573IPW holds active product status, ensuring ongoing availability and manufacturer support. Both parts maintain ROHS3 compliance and carry identical moisture sensitivity ratings, confirming environmental and regulatory equivalence.

The distinction between the two parts is limited to packaging format: the DAC6573IPWG4 is supplied in tape and reel configuration, while the DAC6573IPW is supplied in tube packaging. This difference does not affect electrical performance or functional compatibility in circuit applications.
