TLC7524IPWR Equivalent & Substitute Parts

Part Overview

The TLC7524IPWR 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 delivers unbuffered current output through a parallel data interface. The part maintains active product status with 2,358 units in current inventory stock.

Substitute parts become necessary when addressing specific application requirements such as extended operating temperature ranges, improved linearity specifications, or alternative packaging configurations while maintaining functional equivalence in 8-bit DAC architecture and 16-TSSOP form factor.

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7524IPWR is determined by strict equivalence in the following core parameters:

8-bit resolution with single D/A converter configuration
Current output, unbuffered topology
Parallel data interface with external reference requirement
R-2R resistor ladder architecture
16-TSSOP surface mount package with identical physical dimensions
ROHS3 compliance and MSL Level 1 rating

The AD5424YRUZ series (Analog Devices Inc.) satisfies all substitution criteria across three packaging variants: tube (standard), tape & reel (TR), and cut tape with Digi-Reel (CT). These parts maintain functional and mechanical compatibility while offering enhanced electrical performance characteristics.

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. The AD5424YRUZ series demonstrates superior linearity performance with INL/DNL specifications of ±0.25/±0.5 LSB compared to the TLC7524IPWR at ±0.5/±2.5 LSB. Extended operating temperature range (-40°C to 125°C versus -25°C to 85°C) provides broader environmental applicability.

Supply voltage compatibility requires circuit evaluation: the TLC7524IPWR operates at 5V or 14.5V–15.5V, while AD5424YRUZ variants accept 2.5V–5.5V. Settling time increases marginally from 100ns to 120ns with substitute parts.

Packaging selection among AD5424YRUZ variants depends on procurement and assembly requirements: tube packaging for standard component handling, tape & reel for automated pick-and-place operations, and cut tape with Digi-Reel for mixed-volume applications.

Frequently Asked Questions (FAQ)

Q: Are AD5424YRUZ variants pin-compatible with TLC7524IPWR?

A: Yes. Both components use identical 16-TSSOP packaging with matching physical dimensions (0.173" × 4.40mm width). Pin configuration and functional assignment are equivalent for parallel data interface, external reference, and current output operation.

Q: What is the primary difference between AD5424YRUZ tube, reel, and reel7 packaging?

A: Packaging format only. Tube packaging suits standard component distribution. Tape & reel (TR) accommodates automated assembly equipment. Cut tape with Digi-Reel (CT) provides flexibility for lower-volume or mixed-component orders. Electrical specifications remain identical across all three variants.

Q: Can I substitute TLC7524IPWR with AD5424YRUZ in a 14.5V–15.5V supply application?

A: No. The AD5424YRUZ maximum supply voltage is 5.5V. Applications requiring 14.5V–15.5V operation must retain the TLC7524IPWR or identify alternative components rated for this voltage range.

Q: How do linearity specifications affect substitution?

A: The AD5424YRUZ provides tighter INL/DNL tolerances (±0.25/±0.5 LSB) compared to TLC7524IPWR (±0.5/±2.5 LSB). This represents improved accuracy and reduced conversion error, beneficial for precision measurement applications. Substitution is valid where equal or better linearity is acceptable.

Q: What inventory considerations apply to these substitutes?

A: AD5424YRUZ (tube) maintains 1,777 units in stock. AD5424YRUZ-REEL provides 3,262 units. AD5424YRUZ-REEL7 offers 3,676 units. TLC7524IPWR inventory stands at 2,358 units. Availability varies by packaging format and procurement timeline.
