TLC7528CNSR Equivalent & Substitute Parts

Part Overview

The TLC7528CNSR is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring dual current output channels. This active product features parallel data interface, external reference capability, and R-2R architecture suitable for industrial and instrumentation systems. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7528CNSR is determined by the following critical parameters:

• 8-bit resolution with dual DAC channels
• Parallel data interface with external reference configuration
• Current output, unbuffered topology
• R-2R resistor ladder architecture
• Supply voltage range: 5V to 15V (both analog and digital)
• Operating temperature range: 0°C to 70°C
• Surface mount 20-pin SOIC package format
• ROHS3 compliance and MSL Level 1 rating

The MX7528JCWP+ (Analog Devices Inc./Maxim Integrated) meets these core functional requirements. Differences in settling time (400ns vs. 100ns) and INL/DNL specifications (±1 LSB vs. ±0.5 LSB) represent performance variations within acceptable tolerance for many applications but must be evaluated against specific circuit timing and accuracy requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TLC7528CNSR and MX7528JCWP+ are active products with ROHS3 compliance and MSL Level 1 ratings, meeting regulatory requirements for industrial and commercial applications. Selection between these parts depends on application-specific performance requirements:

The TLC7528CNSR provides faster settling time (100ns) and tighter linearity specifications (±0.5 LSB INL/DNL), suitable for applications requiring rapid conversion cycles and high accuracy.

The MX7528JCWP+ operates with extended settling time (400ns) and relaxed linearity tolerance (±1 LSB INL/DNL), appropriate for applications where conversion speed and precision are less critical.

Package width differences (5.30mm vs. 7.50mm) may affect PCB layout considerations but do not impact electrical compatibility given identical pin configurations and functional specifications.

Frequently Asked Questions (FAQ)

Q: Can MX7528JCWP+ directly replace TLC7528CNSR in existing designs?

A: Direct replacement is possible if the application tolerates the longer settling time (400ns vs. 100ns) and relaxed INL/DNL specifications (±1 LSB vs. ±0.5 LSB). Pin configuration and functional interface are identical. PCB layout must accommodate the wider package body (7.50mm vs. 5.30mm).

Q: What are the key differences between these parts?

A: Settling time and linearity specifications differ. The TLC7528CNSR settles faster with tighter accuracy. Both parts share identical resolution, channel count, supply voltage range, temperature range, and data interface architecture.

Q: Are both parts suitable for new designs?

A: Yes. Both are active products with current manufacturing status and full regulatory compliance (ROHS3, MSL Level 1).

Q: Does package size affect electrical performance?

A: No. Package width differences do not alter electrical characteristics. Selection should be based on PCB layout constraints and available board space.

Q: What supply voltages do these parts support?

A: Both parts operate with analog and digital supply voltages ranging from 5V to 15V, providing flexibility for mixed-voltage system designs.
