TLC7524EDR Equivalent & Substitute Parts

Part Overview

The TLC7524EDR is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring parallel interface control with external voltage references. This surface-mount component operates across industrial temperature ranges and delivers current-mode unbuffered output suitable for precision analog signal generation. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and design optimization across compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC7524EDR are qualified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable tolerances for direct substitution:

• 8-bit resolution with single D/A converter architecture
• Parallel data interface with external reference capability
• Current-mode unbuffered output with differential output support
• R-2R converter architecture
• 16-SOIC surface-mount package (0.154", 3.90mm width)
• Operating temperature range of -40°C to 85°C
• RoHS3 compliance and MSL 1 rating

The AD7524JRZ and AD7524JRZ-REEL7 (both Analog Devices Inc. manufactured) meet all core electrical specifications and mechanical requirements. Differences in settling time (500ns versus 100ns for the main part) and packaging format (Tube or Cut Tape & Digi-Reel versus Tape & Reel) do not preclude substitution in applications where the slower settling time is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both AD7524JRZ and AD7524JRZ-REEL7 are qualified substitutes for the TLC7524EDR based on matching electrical specifications, identical package geometry, and equivalent compliance certifications. All three parts maintain ROHS3 compliance, MSL 1 rating, and active product status.

Selection between substitute options depends on procurement and assembly requirements. The AD7524JRZ-REEL7 offers Cut Tape and Digi-Reel packaging suitable for automated pick-and-place assembly operations. The AD7524JRZ in Tube packaging accommodates manual assembly or lower-volume production workflows. Both Analog Devices variants demonstrate higher inventory availability compared to the Texas Instruments main part.

The primary technical consideration is settling time: the TLC7524EDR settles in 100ns while both AD7524 variants require 500ns. This difference is non-critical for applications where conversion speed is not a limiting factor but must be evaluated for high-speed signal processing designs.

Frequently Asked Questions (FAQ)

Q: Can AD7524JRZ and AD7524JRZ-REEL7 be used interchangeably with TLC7524EDR?

A: Yes, both Analog Devices parts are direct electrical and mechanical substitutes. The primary difference is settling time (500ns versus 100ns). Verify that your application timing requirements accommodate the slower settling time before substitution.

Q: What is the difference between AD7524JRZ and AD7524JRZ-REEL7?

A: Both parts are electrically identical. The difference is packaging format: AD7524JRZ ships in Tube packaging, while AD7524JRZ-REEL7 uses Cut Tape and Digi-Reel format. Select based on your assembly process requirements.

Q: Are the supply voltage ranges compatible?

A: The TLC7524EDR specifies discrete voltage levels (5V and 14.5V ~ 15.5V), while AD7524 variants specify continuous ranges (5V ~ 15V). The AD7524 ranges encompass the TLC7524EDR operating points, ensuring compatibility.

Q: Do all three parts support the same data interface?

A: Yes. All three parts use parallel data interface with external voltage reference capability and R-2R architecture, ensuring functional compatibility in existing designs.

Q: Are there any compliance or certification differences?

A: No. All three parts maintain identical RoHS3 compliance, MSL 1 rating, REACH unaffected status, and active product status.
