TLV1571IPW Equivalent & Substitute Parts

Part Overview

The TLV1571IPW is a 10-bit Analog to Digital Converter (ADC) with single-ended input, SAR architecture, and parallel data interface, manufactured by Texas Instruments. This device is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The TLV1571IPW operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital supplies, with a sampling rate of 1.25M samples per second and an operating temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV1571IPW is based on functional and electrical equivalence across the following critical parameters:

• Resolution and Sampling Rate: Both main and substitute parts maintain 10-bit resolution and 1.25M samples per second sampling rate
• Input Configuration: Single-ended input with 1 channel preserved across all parts
• Data Interface and Architecture: Parallel interface with SAR architecture maintained
• Supply Voltage Compatibility: Identical analog and digital supply voltage ranges (2.7V ~ 5.5V)
• Operating Temperature Range: Consistent -40°C to 85°C specification
• Compliance Standards: ROHS3 compliance maintained across all parts

The primary difference between the main part and substitute lies in packaging format and product status, not in core electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

The TLV1571IDW is the manufacturer-recommended substitute for the obsolete TLV1571IPW. Both devices maintain identical electrical specifications and functional performance across all critical parameters including resolution, sampling rate, input configuration, supply voltage ranges, and operating temperature.

Selection between these parts is determined by packaging and board layout requirements:

• TLV1571IPW (24-TSSOP): Smaller footprint (0.173" width) suitable for space-constrained applications. Product status is obsolete; availability is limited to existing inventory.
• TLV1571IDW (24-SOIC): Larger footprint (0.295" width) with active product status and unlimited moisture sensitivity rating. Recommended for new designs and ongoing production due to active availability and superior moisture handling characteristics.

Both parts carry ROHS3 compliance and are suitable for industrial applications across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can TLV1571IDW directly replace TLV1571IPW in existing designs?

A: Electrical replacement is direct due to identical functional specifications. Physical replacement requires PCB layout modification due to different package formats (24-TSSOP vs. 24-SOIC). Pin configuration remains consistent between parts.

Q: What is the primary reason for substitution?

A: The TLV1571IPW is obsolete. The TLV1571IDW is the active equivalent from the same manufacturer with identical electrical performance.

Q: Are there packaging considerations for board redesign?

A: Yes. The TLV1571IPW uses 24-TSSOP packaging (0.173" width), while the TLV1571IDW uses 24-SOIC packaging (0.295" width). PCB footprint and routing must be adjusted accordingly.

Q: Do supply voltage requirements differ between parts?

A: No. Both parts require identical analog and digital supply voltages of 2.7V to 5.5V.

Q: What is the difference in moisture sensitivity ratings?

A: TLV1571IPW has MSL 2 (1 Year), while TLV1571IDW has MSL 1 (Unlimited). The substitute part offers superior moisture handling for storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. Both TLV1571IPW and TLV1571IDW are ROHS3 compliant.
