TLC7524CPWR Equivalent & Substitute Parts

Part Overview

The TLC7524CPWR is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring current output conversion. This component operates with external voltage references and supports parallel data interfaces. The part is currently in active production status with 2,573 units available in inventory.

Substitute parts become necessary when the TLC7524CPWR reaches end-of-life status, when supply constraints occur, or when design requirements demand extended operating temperature ranges or improved electrical specifications beyond the original component's capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7524CPWR is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resolution: 8 bits
• Number of D/A Converters: 1
• Output Type: Current - Unbuffered
• Data Interface: Parallel
• Reference Type: External
• Architecture: R-2R
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Allowed Variation Parameters:

• Settling Time: May differ (original: 100ns)
• Voltage Supply Ranges: May be broader (original: 5V, 14.5V ~ 15.5V)
• INL/DNL Specifications: May be tighter (original: ±0.5 Max, ±2.5 Max)
• Operating Temperature Range: May be extended (original: 0°C ~ 70°C)

All substitute parts listed (AD5424YRUZ variants) maintain identical core functionality while offering improved or equivalent electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three AD5424YRUZ variants are functionally equivalent substitutes for the TLC7524CPWR. Selection between variants depends on packaging and procurement requirements:

AD5424YRUZ (Tube Packaging): Suitable for low-volume applications and manual assembly processes. Inventory: 1,777 units.

AD5424YRUZ-REEL (Tape & Reel Packaging): Optimized for automated pick-and-place assembly in medium to high-volume production. Inventory: 3,262 units.

AD5424YRUZ-REEL7 (Cut Tape & Digi-Reel Packaging): Provides flexibility for both manual and automated assembly with highest available inventory. Inventory: 3,676 units.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. The AD5424YRUZ series offers improved linearity specifications (±0.25 Max INL vs. ±0.5 Max) and extended operating temperature range (-40°C ~ 125°C vs. 0°C ~ 70°C), providing enhanced performance margins for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can AD5424YRUZ variants directly replace TLC7524CPWR in existing designs?

A: Yes. All substitute parts share identical pin configuration, package dimensions (16-TSSOP), and core functional specifications (8-bit resolution, parallel interface, external reference, R-2R architecture, current output). No PCB redesign is required.

Q: What are the key differences between TLC7524CPWR and AD5424YRUZ?

A: The primary differences are: (1) Settling time increases from 100ns to 120ns; (2) Supply voltage range expands from 5V/14.5V-15.5V to 2.5V-5.5V; (3) Linearity improves from ±0.5/±2.5 LSB to ±0.25/±0.5 LSB; (4) Operating temperature extends from 0°C-70°C to -40°C-125°C.

Q: Which AD5424YRUZ packaging variant should I select?

A: Selection depends on assembly method. Use Tube (AD5424YRUZ) for manual assembly or prototyping. Use Tape & Reel (AD5424YRUZ-REEL) for standard automated assembly. Use Cut Tape & Digi-Reel (AD5424YRUZ-REEL7) for mixed-volume production requiring flexibility.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All listed parts maintain ROHS3 compliance and REACH unaffected status, matching the original TLC7524CPWR specifications.

Q: Does the 20ns increase in settling time affect circuit performance?

A: Settling time impact depends on application bandwidth requirements. The AD5424YRUZ settling time of 120ns remains suitable for most data acquisition applications. Verify against your specific timing specifications.

Q: Can I mix packaging variants in the same production run?

A: Yes. All AD5424YRUZ variants are electrically and functionally identical. Packaging differences affect only procurement and assembly logistics, not circuit performance.
