DAC8564IBPWR Equivalent & Substitute Parts

Part Overview

The DAC8564IBPWR is a 16-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, featuring four independent D/A conversion channels in a 16-TSSOP surface mount package. This component is designed for applications requiring precision voltage output with buffered outputs, supporting both SPI and DSP data interfaces with configurable internal or external voltage references.

The DAC8564IBPWR is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from the same manufacturer family, offering identical electrical performance and mechanical compatibility while maintaining active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC8564IBPWR is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: All substitute parts maintain 16-bit resolution with 4 independent D/A converters
• Electrical Performance: Identical settling time (10µs), output type (voltage-buffered), data interfaces (SPI/DSP), and reference configuration (external/internal)
• Supply Voltage Specifications: All parts operate within 2.7V ~ 5.5V for both analog and digital supplies
• Accuracy Specifications: INL/DNL values remain ±4 / ±0.5 LSB across all equivalents
• Package and Mounting: All substitute parts use 16-TSSOP surface mount packaging with identical physical dimensions
• Compliance and Environmental: All parts maintain ROHS3 compliance, MSL Level 1, and identical operating temperature range

The substitute parts differ only in product status (active vs. discontinued) and packaging format (Cut Tape, Tape & Reel, or unspecified), which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are parametrically equivalent to the DAC8564IBPWR and are suitable for direct replacement in applications requiring 16-bit, 4-channel digital-to-analog conversion with buffered voltage outputs.

Primary Selection Criteria:

• DAC8564IAPWR and DAC8564ICPWR maintain the identical base product number (DAC8564) with active product status and higher inventory availability (2052 and 1079 units respectively). These are the preferred substitutes for new designs or immediate procurement needs.

• DAC8565IAPWR and DAC8565IBPWR use an alternative base product number (DAC8565) but maintain full electrical and mechanical equivalence. DAC8565IAPWR offers the highest inventory level (3400 units) among all substitutes.

All substitute parts comply with ROHS3 regulations, maintain MSL Level 1 moisture sensitivity classification, and operate across the identical temperature range (-40°C ~ 105°C). Packaging format differences (Cut Tape, Tape & Reel) do not affect electrical performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can DAC8564IAPWR, DAC8564ICPWR, DAC8565IAPWR, and DAC8565IBPWR be used interchangeably with DAC8564IBPWR?

A: Yes. All substitute parts maintain identical electrical specifications including 16-bit resolution, 4-channel configuration, 10µs settling time, buffered voltage output, SPI/DSP data interfaces, and 2.7V ~ 5.5V supply voltage range. The 16-TSSOP package and pin configuration are identical across all parts.

Q: What is the difference between DAC8564 and DAC8565 base product numbers?

A: Both base product numbers are parametrically equivalent for the specified electrical and mechanical parameters. The difference is designated by the manufacturer but does not affect substitution compatibility for this application.

Q: Does packaging format (Cut Tape, Tape & Reel) affect circuit performance?

A: No. Packaging format affects only procurement and handling logistics. Electrical performance, mechanical compatibility, and circuit functionality remain identical regardless of packaging format.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and are REACH unaffected, meeting the same environmental and regulatory standards as the original DAC8564IBPWR.

Q: Which substitute part should be selected for new designs?

A: DAC8564IAPWR or DAC8564ICPWR are recommended for new designs due to active product status and availability. DAC8565IAPWR offers the highest inventory level if procurement speed is critical.
