DAC8565IBPW Equivalent & Substitute Parts

Part Overview

The DAC8565IBPW is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring four independent voltage output channels. This active product operates across a wide supply voltage range (2.7V to 5.5V) and supports both SPI and DSP data interfaces with external or internal reference configurations. The component is housed in a 16-TSSOP surface-mount package with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when design requirements necessitate alternative inventory availability, different temperature grade specifications, or equivalent functional performance across the DAC8564 and DAC8565 product families while maintaining identical electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the DAC8565IBPW are qualified based on strict electrical and mechanical parameter equivalence. All identified substitutes maintain identical specifications across the following critical parameters:

16-bit resolution with 4 independent D/A converter channels
10µs settling time performance
Buffered voltage output configuration
SPI and DSP interface support
External and internal reference capability
2.7V to 5.5V dual supply voltage range
±4 LSB INL and ±0.5 LSB DNL linearity specifications
String DAC architecture
-40°C to 105°C operating temperature range
16-TSSOP surface-mount package (0.173" width, 4.40mm)
ROHS3 compliance and MSL Level 1 rating

Substitutes are differentiated by base product number (DAC8564 or DAC8565) and temperature grade designation (A, C, or D suffix), which do not affect functional equivalence within the specified operating parameters.

Engineering Selection Recommendations

All substitute parts maintain active product status with ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001). Selection between DAC8565IBPW and substitute variants should be based on:

Inventory availability requirements
Temperature grade specifications (A, C, D, or B suffix designations)
Base product family preference (DAC8564 or DAC8565)
Supply chain lead time considerations

All parts are functionally interchangeable within applications requiring 16-bit, 4-channel voltage output DAC functionality with the specified electrical and mechanical parameters. No design modifications are required when substituting between qualified alternatives.

Frequently Asked Questions (FAQ)

Q: Can DAC8564 variants substitute for DAC8565IBPW? A: Yes. Both DAC8564 and DAC8565 product families share identical electrical specifications, resolution, channel count, settling time, output configuration, interface protocols, reference options, supply voltage ranges, linearity performance, architecture, operating temperature range, and 16-TSSOP package dimensions. Substitution is electrically and mechanically valid.

Q: What do the temperature grade suffixes (A, B, C, D, I) indicate? A: Temperature grade designations reflect qualification and binning specifications within the -40°C to 105°C operating range. All variants listed maintain the same full operating temperature specification and are functionally equivalent for applications within this range.

Q: Are all substitute parts in the same package? A: Yes. All substitute parts use the 16-TSSOP surface-mount package with 0.173" width and 4.40mm body dimension. PCB layout and footprint compatibility is maintained across all variants.

Q: Do substitute parts require different firmware or software configuration? A: No. All substitute parts support identical SPI and DSP data interfaces with equivalent protocol specifications. Existing firmware and software configurations are directly compatible without modification.

Q: What is the difference between external and internal reference operation? A: All substitute parts support both external reference (user-supplied voltage) and internal reference configurations. Reference type selection is application-dependent and does not affect part substitution eligibility.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification with MSL Level 1 (unlimited moisture sensitivity rating) and REACH Unaffected status.
