ADS7815UG4 Equivalent & Substitute Parts

Part Overview

The ADS7815UG4 is a 16-bit Analog to Digital Converter (ADC) with single-ended input, SAR architecture, and parallel data interface, manufactured by Texas Instruments in 28-SOIC surface mount packaging. The device features 1 input channel, 250k samples per second sampling rate, and dual supply capability (±5V analog, 5V digital).

The ADS7815UG4 is classified as Obsolete, which necessitates identification of equivalent substitute components for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS7815UG4 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Resolution: 16 bits
• Sampling Rate: 250k samples per second
• Input Configuration: 1 single-ended input
• Data Interface: Parallel
• Architecture: SAR (Successive Approximation Register)
• Supply Voltages: ±5V analog, 5V digital
• Operating Temperature Range: -25°C ~ 85°C
• Package: 28-SOIC surface mount
• Compliance: ROHS3 Compliant, REACH Unaffected

All identified substitute parts maintain these specifications without deviation, ensuring functional and mechanical compatibility with the original ADS7815UG4 design.

Engineering Selection Recommendations

ADS7815U (MFR Recommended Substitute): The ADS7815U is the manufacturer-recommended substitute for the obsolete ADS7815UG4. This part maintains identical electrical and mechanical specifications with Last Time Buy status, indicating extended availability. The ADS7815U is supplied in Tube packaging and carries full ROHS3 compliance and REACH Unaffected certification. Current inventory of 1137 pieces supports production requirements.

ADS7811U (Parametric Equivalent): The ADS7811U qualifies as a parametric equivalent, matching all critical electrical specifications and mechanical requirements of the ADS7815UG4. This part also carries Last Time Buy status with 1500 pieces in current inventory. ROHS3 compliance and REACH Unaffected certification are maintained. The ADS7811U is supplied in Tube packaging and represents an alternative source for design continuity.

Both substitute parts are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can ADS7815U and ADS7811U be used interchangeably with ADS7815UG4? A: Yes. Both substitute parts maintain identical electrical specifications (16-bit resolution, 250k sampling rate, ±5V/5V supply, single-ended input, parallel interface) and mechanical compatibility (28-SOIC package, surface mount). Direct substitution is supported without circuit modification.

Q: What is the difference between ADS7815U and ADS7811U? A: Both parts are electrically and mechanically equivalent to the ADS7815UG4. The primary difference is the base product number designation (ADS7815 vs. ADS7811). All critical parameters, package specifications, and compliance certifications are identical.

Q: Why is the ADS7815UG4 classified as Obsolete? A: The ADS7815UG4 has reached end-of-life status. Substitute parts (ADS7815U and ADS7811U) are classified as Last Time Buy, indicating limited future availability. Transition to substitute parts is recommended for new designs and ongoing production.

Q: Are there packaging differences between the main part and substitutes? A: The ADS7815UG4 packaging is not specified in available data. Both substitute parts (ADS7815U and ADS7811U) are supplied in Tube packaging. The 28-SOIC surface mount package specification remains consistent across all parts.

Q: Do the substitute parts meet the same compliance standards? A: Yes. Both ADS7815U and ADS7811U are ROHS3 Compliant and REACH Unaffected, matching the compliance profile of the ADS7815UG4. Moisture Sensitivity Level (MSL) is 3 (168 Hours) for all parts.

Q: What is the current inventory status for substitute parts? A: ADS7815U has 1137 pieces in stock. ADS7811U has 1500 pieces in stock. Both parts are available as new original components.
