TLC7528CDWR Equivalent & Substitute Parts

Part Overview

The TLC7528CDWR is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring dual current output channels. This device features an R-2R architecture with external reference capability and operates across analog and digital supply voltages of 5V to 15V. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified when component availability is constrained or when design flexibility permits selection from qualified alternatives meeting the same electrical and mechanical specifications.

• Current output, unbuffered configuration
• Parallel data interface with external reference
• R-2R architecture
• Analog and digital supply voltage range: 5V ~ 15V
• Operating temperature range: 0°C ~ 70°C

Mechanical Compatibility Parameters:

• 20-SOIC package format (0.295", 7.50mm width)
• Surface mount mounting type

Compliance & Certification:

• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The identified substitute parts MX7528JCWP+ and MX7528KCWP+ (Analog Devices Inc./Maxim Integrated) meet all core electrical and mechanical requirements. Variations in settling time and INL/DNL specifications are within acceptable tolerance ranges for this device category and do not preclude functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

TLC7528CDWR (Primary Selection) Select this part when Texas Instruments sourcing is preferred or when the 100ns settling time specification is required for the application. Active production status and full RoHS3 compliance support long-term availability and regulatory requirements.

MX7528KCWP+ (Preferred Substitute) This part provides the closest electrical match to the TLC7528CDWR with INL specification of ±0.5 LSB (matching the primary part) while maintaining identical mechanical compatibility and compliance certifications. The 400ns settling time represents a 4x increase but remains suitable for standard data acquisition applications not requiring sub-microsecond response times.

MX7528JCWP+ (Alternative Substitute) This part meets all core functional and mechanical requirements with relaxed INL/DNL specifications (±1 LSB). Selection is appropriate when application tolerance permits reduced linearity performance and when Analog Devices/Maxim sourcing is advantageous.

All three parts share identical package geometry, supply voltage ranges, operating temperature specifications, and compliance certifications, enabling direct substitution at the board level without design modification.

Frequently Asked Questions (FAQ)

Q: Can MX7528JCWP+ and MX7528KCWP+ be used interchangeably with TLC7528CDWR?

A: Both Maxim parts are functionally equivalent for applications where the 400ns settling time and specified INL/DNL tolerances are acceptable. The 20-SOIC package geometry is identical, and all three parts operate across the same supply voltage and temperature ranges. Direct substitution is possible without PCB redesign.

Q: What is the primary difference between MX7528JCWP+ and MX7528KCWP+?

A: The MX7528KCWP+ provides tighter INL specification (±0.5 LSB vs. ±1 LSB) and is the preferred substitute when linearity performance closely matches the TLC7528CDWR. Both parts share identical settling time and DNL specifications.

Q: Does settling time difference affect circuit design?

A: The TLC7528CDWR settles in 100ns while both Maxim alternatives settle in 400ns. Applications requiring conversion rates exceeding 2.5 MHz may require design consideration. Standard data acquisition applications operating at lower conversion rates are unaffected by this difference.

Q: Are all three parts RoHS3 compliant?

A: Yes. TLC7528CDWR, MX7528JCWP+, and MX7528KCWP+ are all ROHS3 compliant with MSL rating of 1 (Unlimited), meeting regulatory requirements for commercial and industrial applications.

Q: What packaging formats are available?

A: TLC7528CDWR is supplied in Cut Tape (CT) and Digi-Reel format. MX7528JCWP+ and MX7528KCWP+ are supplied in Tube packaging. All three use identical 20-SOIC surface mount package geometry.
