Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC0834ING4 is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit ADC
• Sampling Rate: 20k samples per second
• Input Configuration: Support for 2, 3, or 4 inputs with differential, pseudo-differential, and single-ended modes
• Data Interface: SPI protocol
• Architecture: SAR-based conversion
• Supply Voltage: 5V analog and digital supplies
• Package: 14-DIP through-hole form factor
• Temperature Range: -40°C to 85°C operation
• Compliance: ROHS3 and REACH requirements

Parts meeting all these specifications are classified as direct equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The TLC0834IN is the manufacturer-recommended substitute for the discontinued TLC0834ING4. Both parts share identical electrical specifications, pin configuration, and functional characteristics. The primary distinction is product status: TLC0834ING4 is discontinued, while TLC0834IN maintains active production status.

Selection of TLC0834IN ensures:

• Continued availability from active inventory
• Identical functional performance in existing circuit designs
• Full compliance with ROHS3 and REACH regulatory requirements
• Compatibility with through-hole PCB assembly processes
• No circuit redesign or validation required

Frequently Asked Questions (FAQ)

Q: Can TLC0834IN be used as a direct replacement for TLC0834ING4?

A: Yes. Both parts are electrically and functionally identical 8-bit SAR ADCs with 20k samples per second sampling rate, SPI interface, and 5V supply requirements. Pin configuration and package form factor (14-DIP) are identical. No circuit modifications are required.

Q: What is the difference between TLC0834ING4 and TLC0834IN?

A: The primary difference is product status. TLC0834ING4 is discontinued at DiGi Electronics, while TLC0834IN is in active production. All electrical parameters, performance specifications, and compliance certifications are identical.

Q: Are there any packaging differences between these parts?

A: TLC0834IN is supplied in Tube packaging, while TLC0834ING4 packaging is not specified. Both use the same 14-PDIP through-hole package form factor. Packaging differences do not affect electrical performance or PCB compatibility.

Q: Do both parts support the same input configurations?

A: Yes. Both TLC0834ING4 and TLC0834IN support 2, 3, or 4 analog inputs with differential, pseudo-differential, and single-ended input modes. Input configuration flexibility is identical.

Q: Are regulatory certifications identical?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. Export classification (ECCN EAR99) and tariff codes (HTSUS 8542.39.0001) are identical.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 85°C, suitable for industrial and commercial temperature environments.
