TS1004IT14 Equivalent & Substitute Parts

Part Overview

The TS1004IT14 is a general-purpose operational amplifier integrated circuit manufactured by Silicon Labs, configured as a 4-circuit rail-to-rail amplifier in a 14-TSSOP surface mount package. This device is classified as obsolete, making identification of functionally equivalent substitute components necessary for ongoing design support, maintenance, and production continuity. The TS1004IT14 operates across a supply voltage range of 0.65V to 2.5V with ultra-low supply current consumption, making it suitable for low-power applications requiring multiple amplifier stages in a compact form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TS1004IT14 is determined by strict alignment of the following core parameters:

Mandatory Matching Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 4
• Output Type: Rail-to-Rail
• Package / Case: 14-TSSOP
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 85°C
• Moisture Sensitivity Level: 1 (Unlimited)

Compatibility Considerations: The substitute part must accommodate the TS1004IT14's supply voltage range of 0.65V to 2.5V. Substitute devices with extended supply voltage ranges remain compatible, provided they operate within the original specification window. Pin configuration and functional pinout must remain identical to ensure direct board-level replacement without circuit modification.

The MAX4472EUD+ from Analog Devices Inc./Maxim Integrated satisfies all mandatory matching criteria and is classified as an active product, ensuring long-term availability and supply chain stability.

Engineering Selection Recommendations

Primary Substitute: MAX4472EUD+

The MAX4472EUD+ is the recommended substitute for the obsolete TS1004IT14. This selection is based on the following factors:

Product Status and Availability: The MAX4472EUD+ maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring continued manufacturing, documentation support, and supply chain availability. The TS1004IT14's obsolete classification creates long-term sourcing risk; transition to an active equivalent mitigates supply discontinuation.

Compliance and Certifications: Both devices share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, ensuring equivalent export control and tariff treatment. The MAX4472EUD+ is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Functional Compatibility: The MAX4472EUD+ maintains identical package geometry (14-TSSOP), pinout configuration, and core functional specifications (4-circuit general-purpose rail-to-rail amplifier). Direct board-level substitution is supported without circuit redesign.

Performance Characteristics: The MAX4472EUD+ demonstrates improved performance metrics relative to the TS1004IT14: higher slew rate (0.002V/µs vs. 0.0015V/µs), increased gain bandwidth product (9 kHz vs. 4 kHz), and significantly higher output current capability (36 mA vs. 1.5 mA per channel). These enhancements provide design margin and support higher-performance applications.

Supply Voltage Consideration: The MAX4472EUD+ operates across 1.8V to 5.5V, which encompasses the TS1004IT14's 0.65V to 2.5V range. Applications operating at the TS1004IT14's minimum supply voltage (0.65V) require verification that the MAX4472EUD+ minimum specification (1.8V) aligns with system requirements. For applications operating within 1.8V to 2.5V, direct substitution is supported without modification.

Frequently Asked Questions (FAQ)

Q: Can the MAX4472EUD+ directly replace the TS1004IT14 on existing PCBs?

A: Yes, direct board-level replacement is supported. Both devices use identical 14-TSSOP packaging with matching pinout configuration and surface mount footprint. No circuit modification or PCB rework is required for mechanical and electrical compatibility.

Q: What is the primary reason for substituting the TS1004IT14?

A: The TS1004IT14 is classified as obsolete, creating long-term supply risk. The MAX4472EUD+ is an active product with confirmed manufacturing continuity, ensuring reliable component availability for production and maintenance applications.

Q: Are there supply voltage limitations when substituting to the MAX4472EUD+?

A: The MAX4472EUD+ minimum supply voltage is 1.8V, compared to the TS1004IT14's 0.65V minimum. Applications operating below 1.8V require alternative solutions. For applications within the 1.8V to 2.5V range, the MAX4472EUD+ operates within both device specifications.

Q: How do the performance characteristics compare?

A: The MAX4472EUD+ provides improved slew rate (0.002V/µs vs. 0.0015V/µs), higher gain bandwidth product (9 kHz vs. 4 kHz), and substantially higher output current per channel (36 mA vs. 1.5 mA). Input offset voltage remains identical at 500 µV. These improvements support higher-performance applications while maintaining backward compatibility.

Q: What is the supply current difference between these devices?

A: The MAX4472EUD+ consumes 750 nA across 4 channels, compared to the TS1004IT14's 2.4 µA. The MAX4472EUD+ provides superior power efficiency, reducing overall system current draw by approximately 69%.

Q: Are regulatory and compliance classifications identical?

A: Yes. Both devices share ECCN EAR99 and HTSUS 8542.33.0001 classifications. The MAX4472EUD+ is RoHS3 Compliant and REACH Unaffected, meeting current environmental standards.

Q: What is the input bias current difference?

A: The TS1004IT14 specifies 25 pA input bias current, while the MAX4472EUD+ specifies 200 pA. For applications with high-impedance input sources, this difference may require circuit analysis to confirm acceptable performance.

Q: Is the 14-TSSOP package identical between both devices?

A: Yes. Both devices use 14-TSSOP packaging with 0.173" (4.40mm) width. Footprint, lead pitch, and solder pad geometry are identical, supporting direct PCB compatibility.
