TLC7226IDWR Equivalent & Substitute Parts

Part Overview

The TLC7226IDWR is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, featuring 4 independent D/A converters in a 20-SOIC surface mount package. This component is classified as active product status and is designed for data acquisition applications requiring parallel interface voltage output conversion with external reference capability. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7226IDWR is determined by the following critical parameters:

• Resolution and Converter Count: 8-bit resolution with 4 independent D/A converters
• Package Compatibility: 20-SOIC surface mount package (0.295", 7.50mm Width)
• Interface Type: Parallel data interface with external reference
• Output Configuration: Voltage-buffered output
• Architecture: R-2R ladder network
• Supply Voltage Ranges: Analog supply 11.4V ~ 16.5V and -5V minimum
• Operating Temperature Range: Minimum -30°C capability
• Compliance: ROHS3 compliant, REACH unaffected

Substitute parts must maintain compatibility across these parameters. Variations in settling time, DNL/INL specifications, and MSL rating are permissible when the core functional and mechanical requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance. Selection between TLC7226IDWR and substitute options should be based on the following factors:

AD7226KRZ and AD7226KRZ-REEL: These Analog Devices parts offer improved settling time (4µs versus 20µs) and tighter INL specifications (±0.5 LSB maximum). The primary distinction between these two is packaging format: AD7226KRZ is supplied in Tube packaging, while AD7226KRZ-REEL is supplied in Cut Tape and Digi-Reel format. Both require MSL 3 handling (168 hours), which differs from the TLC7226IDWR MSL 1 rating.

MX7226KEWP+: This Analog Devices/Maxim Integrated part provides improved settling time (4µs) while maintaining MSL 1 (Unlimited) moisture sensitivity rating, matching the TLC7226IDWR in this regard. INL/DNL specifications are equivalent to the original part (±1 LSB maximum). Packaging is supplied in Tube format.

All substitute parts support the required operating temperature range and maintain identical package geometry, making them mechanically and electrically compatible within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can AD7226KRZ be used as a direct replacement for TLC7226IDWR?

A: Yes, within the constraints of your application requirements. Both parts share identical resolution (8-bit), converter count (4), package type (20-SOIC), and interface specifications (parallel, external reference, voltage-buffered output). The AD7226KRZ offers superior settling time (4µs versus 20µs) and tighter INL accuracy (±0.5 LSB). However, the AD7226KRZ requires MSL 3 handling (168 hours) compared to the TLC7226IDWR MSL 1 rating, which may impact storage and assembly procedures.

Q: What is the difference between AD7226KRZ and AD7226KRZ-REEL?

A: Both parts are electrically identical 8-bit, 4-channel DACs from Analog Devices with matching electrical specifications. The distinction is packaging format: AD7226KRZ is supplied in Tube packaging, while AD7226KRZ-REEL is supplied in Cut Tape and Digi-Reel format. Selection depends on your assembly process requirements and inventory management preferences.

Q: Why does MX7226KEWP+ have faster settling time than TLC7226IDWR?

A: Settling time is determined by the internal circuit design and architecture implementation. While both parts use R-2R ladder architecture and share identical resolution and converter configuration, the MX7226KEWP+ achieves 4µs settling time compared to the TLC7226IDWR 20µs specification. This represents a design difference between manufacturers and does not affect functional compatibility when settling time requirements permit faster operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (AD7226KRZ, AD7226KRZ-REEL, and MX7226KEWP+) maintain ROHS3 compliance status, matching the TLC7226IDWR compliance profile.

Q: What is the significance of MSL rating differences?

A: Moisture Sensitivity Level (MSL) determines the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before requiring baking. TLC7226IDWR and MX7226KEWP+ are rated MSL 1 (Unlimited), meaning no time restriction. AD7226KRZ and AD7226KRZ-REEL are rated MSL 3 (168 hours), requiring baking if storage or handling exceeds this duration. This affects supply chain logistics and assembly procedures but does not impact electrical performance.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use identical 20-SOIC package geometry (0.295", 7.50mm Width) with surface mount configuration, ensuring mechanical compatibility with existing PCB layouts and reflow soldering processes.
