TLC7528IPWG4 Equivalent & Substitute Parts

Part Overview

The TLC7528IPWG4 is an 8-bit digital-to-analog converter (DAC) with dual output channels, designed for data acquisition applications requiring parallel interface control and external voltage reference configuration. This component features current-unbuffered output architecture with R-2R ladder topology and is packaged in a 20-TSSOP surface mount configuration.

The TLC7528IPWG4 is discontinued at DiGi Electronics. Equivalent substitute parts are available from Texas Instruments and Analog Devices Inc., offering identical or enhanced electrical and mechanical compatibility for direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7528IPWG4 is determined by the following critical parameters:

• Resolution & Channel Count: 8-bit resolution with 2 D/A converters (non-negotiable)
• Package & Pinout: 20-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Interface Architecture: Parallel data interface with external voltage reference and R-2R ladder topology
• Output Configuration: Current-unbuffered output type
• Supply Voltage Compatibility: Analog and digital supply voltage ranges must accommodate the design's power distribution

The substitute parts TLC7528IPW, AD5428YRUZ, and AD5428YRUZ-REEL7 maintain identical core functionality and package specifications. Differences in settling time, supply voltage ranges, temperature operating limits, and linearity specifications are secondary parameters that may enhance performance in specific applications but do not prevent direct substitution in designs originally specified for the TLC7528IPWG4.

Parameter Comparison

Engineering Selection Recommendations

TLC7528IPW (Texas Instruments): This part is the direct equivalent from the original manufacturer, maintaining identical electrical specifications and operating temperature range. It is currently in active production status with higher inventory availability (1421 pcs). Selection of this part ensures continuity with the original design intent and manufacturer support. Packaging is supplied in Tube format.

AD5428YRUZ (Analog Devices Inc.): This substitute offers enhanced linearity performance (±0.25 LSB INL vs. ±0.5 LSB) and extended operating temperature range (-40°C ~ 125°C vs. -25°C ~ 85°C). However, the supply voltage range is restricted to 2.5V ~ 5.5V, which may not be compatible with designs requiring the full 5V ~ 15V range of the original part. This part is in active production status. Packaging is supplied in Tube format.

AD5428YRUZ-REEL7 (Analog Devices Inc.): Functionally identical to AD5428YRUZ with the same electrical specifications and temperature range. The primary distinction is packaging format (Cut Tape & Digi-Reel®), which is suitable for high-volume automated assembly. Inventory availability is highest among all substitutes (3074 pcs). Selection of this part is appropriate for production environments requiring reel-based component feeding.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring environmental and moisture handling compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TLC7528IPW be used as a direct replacement for TLC7528IPWG4?

A: Yes. TLC7528IPW is the active production equivalent from Texas Instruments with identical electrical specifications, operating temperature range, and 20-TSSOP package configuration. The primary difference is product status (active vs. discontinued) and packaging format (Tube vs. original packaging).

Q: What is the key limitation when substituting AD5428YRUZ or AD5428YRUZ-REEL7?

A: The supply voltage range is restricted to 2.5V ~ 5.5V, compared to the original 5V ~ 15V specification. Designs requiring analog or digital supply voltages above 5.5V are not compatible with Analog Devices substitutes. Verify your power supply configuration before selection.

Q: Are the AD5428 parts pin-compatible with the TLC7528IPWG4?

A: Yes. All substitute parts use the identical 20-TSSOP package with matching pinout, enabling direct PCB-level replacement without layout modifications.

Q: What is the difference between AD5428YRUZ and AD5428YRUZ-REEL7?

A: Both parts are electrically and functionally identical. The difference is packaging format: AD5428YRUZ is supplied in Tube packaging for lower-volume applications, while AD5428YRUZ-REEL7 is supplied on Cut Tape with Digi-Reel® for automated high-volume assembly processes.

Q: Does the 20ns difference in settling time (100ns vs. 120ns) affect substitution compatibility?

A: The settling time difference is a secondary performance parameter. For applications with timing-critical signal acquisition, verify that the 120ns settling time of AD5428 parts meets your system requirements. For most standard data acquisition applications, this difference is not functionally significant.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLC7528IPW, AD5428YRUZ, and AD5428YRUZ-REEL7 are all ROHS3 compliant with MSL Level 1 moisture sensitivity rating, matching the environmental compliance of the original TLC7528IPWG4.
