LM98714CCMT

Analog Front End (AFE) Overview

The LM98714CCMT is a Texas Instruments analog front-end (AFE) integrated circuit designed for high-speed data acquisition. It features three independent channels with 16-bit resolution and supports a sampling rate of 45 MSPS. The device incorporates an internal digital copier function, allowing for flexible signal routing and processing within the chip. It operates on dual power supplies ranging from 3V to 3.6V for both analog and digital sections. Packaged in a 48-TSSOP (0.240", 6.10mm wide) surface-mount enclosure, it delivers low power consumption suitable for portable applications.

Analog Front End (AFE) Feature Summary

• Three-channel architecture with 16-bit resolution
• High-speed sampling capability up to 45 MSPS
• Integrated digital copier for signal management
• Low voltage operation (3V to 3.6V)

Analog Front End (AFE) Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered data acquisition devices

Analog Front End (AFE) Procurement Notes

Verify the specific suffix (e.g., NOPB) as the base model number may refer to multiple packaging or environmental variants. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) prior to ordering. Check for active production status versus obsolescence notices, as availability may vary by distributor lot.

Analog Front End (AFE) Selection Notes

Select this component when multi-channel, mid-resolution data acquisition is required at moderate speeds. Ensure the design accommodates the 48-pin TSSOP footprint and thermal requirements. Compare against higher-speed or higher-resolution alternatives if system demands exceed 45 MSPS or 16-bit precision.

Analog Front End (AFE) Part Context

This part belongs to the LM98714 family of analog front-ends from Texas Instruments. Variants such as LM98714BCMTX/NOPB share similar core specifications but may differ in temperature grades, packaging quantities, or specific feature enablement. The CCMT designation typically indicates a commercial temperature range variant.

Analog Front End (AFE) Replacement Considerations

Direct pin-to-pin replacements should be verified against the official TI substitution guide. Cross-reference with other members of the LM98714 series for potential functional equivalents that match the required channel count and resolution.
