LM98714CCMT Equivalent & Substitute Parts

Part Overview

The LM98714CCMT is a 3-channel, 16-bit analog front-end (AFE) integrated circuit manufactured by Texas Instruments, designed for data acquisition applications. It operates at 610 mW power consumption and supports dual supply voltages of 3V to 3.6V for both analog and digital domains. The device is packaged in a 48-TSSOP surface mount package.

The LM98714CCMT is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM98714CCMT is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 16-bit resolution with 3 channels
• Power Consumption: 610 mW maximum
• Supply Voltage Ranges: Analog supply 3V ~ 3.6V; Digital supply 3V ~ 3.6V
• Package Compatibility: 48-TSSOP surface mount package with 0.240" (6.10mm) width
• Functional Category: Data acquisition analog front-end

Only parts meeting all these criteria are classified as direct substitutes. The LM98714CCMT/NOPB variant qualifies as a direct substitute based on identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The LM98714CCMT/NOPB is a direct functional equivalent to the LM98714CCMT. Both parts share identical electrical specifications, channel configuration, resolution, power consumption, and package geometry. The primary distinction is product status: the original LM98714CCMT is obsolete, while the LM98714CCMT/NOPB variant maintains active status.

For new designs or system maintenance requiring the LM98714 AFE architecture, the LM98714CCMT/NOPB is the appropriate selection. Both parts carry identical export classification (EAR99) and tariff codes (8542.39.0001), supporting equivalent regulatory and compliance pathways.

Frequently Asked Questions (FAQ)

Q: Can the LM98714CCMT/NOPB be used as a direct replacement for the LM98714CCMT?

A: Yes. Both parts are electrically and mechanically identical. They share the same 16-bit resolution, 3-channel configuration, 610 mW power consumption, 3V to 3.6V dual supply voltage ranges, and 48-TSSOP package footprint. The primary difference is product lifecycle status.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" designation indicates the part is supplied in bulk packaging without lead-free plating. This is a packaging and delivery specification that does not affect electrical performance or functional compatibility.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both the LM98714CCMT and LM98714CCMT/NOPB use the 48-TSSOP package with identical 0.240" (6.10mm) width. PCB footprints, pin assignments, and mechanical mounting requirements are identical.

Q: What is the significance of the obsolete status of the original LM98714CCMT?

A: Obsolete status indicates the part is no longer manufactured or supported by Texas Instruments. The LM98714CCMT/NOPB, maintained by National Semiconductor, provides continued availability and supply chain support for this AFE architecture.

Q: Are the export classifications identical between these parts?

A: Yes. Both parts carry ECCN classification EAR99 and HTSUS code 8542.39.0001, ensuring equivalent regulatory treatment for export and import purposes.
