Parameter Comparison

Engineering Selection Recommendations

Both the DAC7568IAPWR and AD5628BRUZ-1 maintain active product status with full RoHS3 and REACH compliance. Selection between these components should be based on application-specific requirements:

The DAC7568IAPWR offers a wider operating temperature range (-40°C to 125°C) and tighter INL/DNL specifications (±0.3, ±0.05 LSB), making it suitable for high-precision applications across extended thermal environments.

The AD5628BRUZ-1 provides faster settling time (7µs versus 10µs) and operates within the -40°C to 105°C range, with MSL rating of 1 (Unlimited) compared to MSL 2 (1 Year) for the original part. This substitute is appropriate for applications prioritizing faster transient response within standard industrial temperature ranges.

Both components share identical core architecture, interface protocols, supply voltage specifications, and package configuration, ensuring direct functional equivalence in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the AD5628BRUZ-1 directly replace the DAC7568IAPWR in existing designs?

A: Yes. Both components feature identical 12-bit resolution, 8-channel architecture, SPI/DSP interfaces, supply voltage ranges (2.7V–5.5V), and 14-TSSOP package configuration. Pin-level compatibility and functional equivalence are maintained.

Q: What are the key differences between these two parts?

A: The primary differences are settling time (AD5628BRUZ-1: 7µs versus DAC7568IAPWR: 10µs), operating temperature range (AD5628BRUZ-1: -40°C to 105°C versus DAC7568IAPWR: -40°C to 125°C), INL/DNL specifications (AD5628BRUZ-1: ±0.5, ±0.25 LSB Max versus DAC7568IAPWR: ±0.3, ±0.05 LSB), and moisture sensitivity level (AD5628BRUZ-1: MSL 1 Unlimited versus DAC7568IAPWR: MSL 2, 1 Year).

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. No compliance barriers exist for substitution.

Q: Which part should be selected for high-temperature applications?

A: The DAC7568IAPWR supports operation to 125°C, making it the appropriate choice for applications requiring extended upper temperature limits beyond 105°C.

Q: Which part offers better precision?

A: The DAC7568IAPWR provides tighter INL/DNL specifications (±0.3, ±0.05 LSB) compared to the AD5628BRUZ-1 (±0.5, ±0.25 LSB Max), making it suitable for higher-precision measurement and control applications.

Q: Is the 14-TSSOP package identical for both parts?

A: Yes. Both components use the 14-TSSOP package with 0.173" width (4.40mm), ensuring identical PCB footprint and mounting requirements.
