DAC7611P Equivalent & Substitute Parts

Part Overview

The DAC7611P is a 12-bit digital-to-analog converter manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This component features a single voltage-buffered output with SPI data interface and internal reference, operating from dual 5V supplies across the industrial temperature range of -40°C to 85°C. The DAC7611P is classified as "Not For New Designs," making identification of functionally equivalent alternatives essential for ongoing production support and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC7611P is determined by the following core parameters: 12-bit resolution, single D/A converter, voltage-buffered output, SPI data interface compatibility, internal reference architecture, 5V analog and digital supply voltages, -40°C to 85°C operating temperature range, and 8-DIP through-hole package format. Parts meeting these criteria are functionally interchangeable at the system level.

The substitute parts identified fall into two categories:

Package-Compatible Substitutes (Same DIP Package): DAC7611U (surface-mount variant of same base product), AD8300ANZ, DAC8512EPZ, and DAC8512FPZ maintain identical or compatible electrical specifications and package footprint, enabling direct replacement in through-hole applications.

Electrical Compatibility Criteria: All substitutes maintain 12-bit resolution, single converter architecture, voltage-buffered output, SPI interface support, internal reference, 5V supply operation, and -40°C to 85°C temperature range. Settling time and INL/DNL specifications vary within acceptable tolerances for most applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement: AD8300ANZ, DAC8512EPZ, and DAC8512FPZ are recommended as primary substitutes. All three maintain the 8-DIP through-hole package format, identical pin count, and compatible electrical specifications. These parts carry "Active" product status, ensuring long-term availability and manufacturing support.

For Surface-Mount Applications: DAC7611U provides an alternative using the same base product architecture (DAC7611) in 8-SOIC surface-mount packaging. This option is suitable only for designs that can accommodate surface-mount technology.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory requirements of the original DAC7611P.

Supply Voltage Flexibility: AD8300ANZ offers extended supply voltage range (2.7V to 5.5V) compared to the fixed 5V requirement of other options, providing design flexibility for mixed-voltage systems while maintaining full backward compatibility with 5V operation.

Frequently Asked Questions (FAQ)

Q: Can DAC7611U replace DAC7611P in a through-hole PCB design?

A: No. DAC7611U uses 8-SOIC surface-mount packaging, while DAC7611P requires 8-DIP through-hole format. For through-hole applications, select AD8300ANZ, DAC8512EPZ, or DAC8512FPZ instead.

Q: What is the primary reason for finding substitutes for DAC7611P?

A: The DAC7611P is classified as "Not For New Designs" by Texas Instruments. Active alternatives ensure continued availability and manufacturing support for production systems.

Q: Are all substitute parts pin-compatible with DAC7611P?

A: Yes. AD8300ANZ, DAC8512EPZ, and DAC8512FPZ all use 8-DIP through-hole packaging with identical pin assignments, enabling direct socket replacement without PCB modification.

Q: How do settling times differ among the substitutes?

A: DAC7611P and DAC7611U settle in 7µs (typical). AD8300ANZ requires 14µs, while DAC8512EPZ and DAC8512FPZ require 16µs. Applications with strict timing requirements should verify compatibility with the slower settling times of Analog Devices alternatives.

Q: Which substitute offers the best linearity performance?

A: DAC8512EPZ provides the tightest INL specification (±0.25 LSB) among the substitutes. DAC7611P and DAC7611U maintain ±0.5 LSB INL. DAC8512FPZ and AD8300ANZ offer ±0.75 and ±0.5 LSB INL respectively.

Q: Can AD8300ANZ operate at supply voltages below 5V?

A: Yes. AD8300ANZ supports 2.7V to 5.5V operation on both analog and digital supplies, providing flexibility for lower-voltage system designs. Other substitutes require fixed 5V supplies.

Q: Are there any data interface differences between substitutes?

A: DAC7611P supports SPI only. AD8300ANZ, DAC8512EPZ, and DAC8512FPZ support both SPI and DSP interfaces, offering additional communication protocol options without affecting SPI compatibility.
