TLV1562CDW Equivalent & Substitute Parts
Part Overview
The TLV1562CDW is a 10-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for data acquisition applications requiring 2 or 4 differential and single-ended inputs with a 2 MHz sampling rate. The device operates with external voltage references and supports parallel data interface output.
The TLV1562CDW is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. The primary substitute maintains functional compatibility while offering extended operational specifications and active product status.

Substitute Part Grouping Explanation
Substitution of the TLV1562CDW is determined by strict equivalence across the following electrical and mechanical parameters:
- 10-bit resolution requirement
- 2 MHz sampling rate capability
- Support for 2 or 4 input channels with differential and single-ended configurations
- Pipelined architecture with external reference type
- Parallel data interface output
- 28-SOIC surface mount package with identical physical dimensions
- Supply voltage compatibility (2.7V ~ 5.5V for both analog and digital supplies)
- RoHS3 compliance and MSL Level 1 moisture sensitivity rating
The TLV1562IDW meets all these criteria and is classified as the manufacturer-recommended substitute. The primary distinction is product status and operating temperature range expansion.

Engineering Selection Recommendations
The TLV1562IDW is the direct substitute for the TLV1562CDW based on manufacturer designation and full parameter equivalence. Selection of the TLV1562IDW provides the following advantages:
- Active product status ensures ongoing availability and supply chain continuity
- Extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) supports broader environmental deployment scenarios
- Identical electrical specifications and package footprint enable direct board-level replacement without design modification
- ROHS3 compliance and REACH unaffected status maintain regulatory alignment
- MSL Level 1 rating confirms unlimited shelf life storage capability
The substitute part is suitable for new designs, legacy system maintenance, and production continuity where the original part number is no longer available.
Frequently Asked Questions (FAQ)
Q: Can the TLV1562IDW be used as a direct replacement for the TLV1562CDW on existing PCBs?
A: Yes. Both parts share identical package geometry (28-SOIC), pinout, electrical specifications, and functional architecture. No PCB redesign or layout modification is required.
Q: What is the primary difference between these two part numbers?
A: The TLV1562IDW has an extended operating temperature range (-40°C ~ 85°C) compared to the TLV1562CDW (0°C ~ 70°C). The TLV1562IDW is also classified as active product status, whereas the TLV1562CDW is obsolete.
Q: Are there any supply voltage or reference configuration differences?
A: No. Both parts operate with identical analog and digital supply voltage ranges (2.7V ~ 5.5V) and require external voltage references. Configuration and signal routing remain unchanged.
Q: Does the substitute part maintain the same sampling rate and resolution?
A: Yes. Both parts deliver 10-bit resolution at 2 MHz sampling rate with identical pipelined architecture and parallel data interface output.
Q: Are there any compliance or certification differences?
A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 moisture sensitivity rating. Regulatory and environmental compliance is equivalent.
Q: What packaging options are available for the substitute part?
A: The TLV1562IDW is supplied in tube packaging. The original TLV1562CDW packaging specification was not provided in the available data.
