Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC0830LCN/NOPB is determined by the following critical parameters:

• Resolution: 8-bit conversion capability
• Output Configuration: Current output, unbuffered, with differential output support
• Interface Type: Parallel data interface
• Reference Architecture: External voltage reference requirement
• Supply Voltage Compatibility: Analog and digital supply ranges supporting 5V operation minimum
• Operating Temperature Range: 0°C to 70°C
• Package Compatibility: Through-hole DIP mounting

The TLC7524CN qualifies as a functional equivalent based on matching these core electrical and mechanical parameters, despite differences in package pin count and settling time specifications.

Parameter Comparison

Engineering Selection Recommendations

The TLC7524CN is an active product offering functional equivalence to the obsolete DAC0830LCN/NOPB for 8-bit parallel-interface digital-to-analog conversion applications. Both components maintain ROHS3 compliance and support the required operating temperature range of 0°C to 70°C.

Primary design consideration: The TLC7524CN operates in a 16-pin DIP package compared to the 20-pin DIP of the DAC0830LCN/NOPB. PCB layout modification is required to accommodate the reduced pin count. Pin function mapping must be verified against device datasheets to ensure correct signal routing in the target application.

Supply voltage specifications differ slightly between the two parts. The DAC0830LCN/NOPB accepts 5V to 15V on both analog and digital supplies, while the TLC7524CN specifies 5V or 14.5V to 15.5V. Applications operating at intermediate voltages between 5V and 14.5V require validation against the TLC7524CN datasheet.

Frequently Asked Questions (FAQ)

Q: Can the TLC7524CN directly replace the DAC0830LCN/NOPB without circuit modification?

A: Direct socket replacement is not possible due to different DIP package pin counts (16-pin versus 20-pin). PCB redesign is required. Pin function mapping must be verified against both device datasheets.

Q: Are the supply voltage ranges compatible between these parts?

A: Both parts support 5V operation. The DAC0830LCN/NOPB accepts 5V to 15V continuously, while the TLC7524CN specifies discrete voltage points (5V) or a range (14.5V to 15.5V). Applications using intermediate voltages require datasheet verification.

Q: What is the significance of the different settling times?

A: The DAC0830LCN/NOPB specifies 1µs typical settling time, while the TLC7524CN specifies 100ns. The TLC7524CN offers faster settling performance. Application timing requirements determine whether this difference is relevant to system operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the DAC0830LCN/NOPB and TLC7524CN are ROHS3 compliant and REACH unaffected.

Q: What is the product status difference between these parts?

A: The DAC0830LCN/NOPB is classified as obsolete, indicating discontinued manufacturing. The TLC7524CN is active, ensuring ongoing availability and manufacturer support.
