LTC1403AIMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1403AIMSE#TRPBF is a 14-bit, 2.8Msps serial analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 10-lead MSOP package with an exposed ground pad. It operates on a single 3V supply, drawing 5.2mA during active conversion and consuming only 10µW in Sleep mode. The device features differential inputs supporting a 0V to 2.5V unipolar range and includes a 2.5V internal bandgap reference. Key performance metrics include a Signal-to-Noise Plus Distortion Ratio (SINAD) of 70.5dB at 1.4MHz input and a Spurious Free Dynamic Range (SFDR) of 86dB. It utilizes a 3-wire serial interface for data output.

• 14-bit resolution with 2.8Msps sampling rate
• Low power consumption: 14mW active, 10µW Sleep mode
• Differential inputs with 80dB common mode rejection
• Integrated 2.5V internal reference

Analog To Digital Converters (ADC) Applications

• Automotive systems
• Communications equipment
• Data acquisition systems
• Uninterrupted power supplies
• Multiphase motor control

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure the component is sourced as a lead-free finish product compliant with RoHS standards. Check for specific lot traceability requirements if applicable to your manufacturing process.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high-speed 14-bit conversion in a compact form factor. The 14-bit resolution provides finer granularity than the 12-bit LTC1403 variant. Consider the 2.8Msps throughput when designing clocking circuits; a 50.4MHz clock allows full-rate operation with additional acquisition time. Ensure the driving source impedance is low enough to meet the 39ns acquisition time requirement.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1403 family, which also includes 12-bit variants (LTC1403) and different temperature grades (C, I, H). The 'A' suffix denotes the 14-bit version, while 'I' specifies industrial temperature range. The MSE package is a 10-lead plastic MSOP. Other family members share similar pinouts and interfaces but differ in resolution and thermal specifications.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical parameter overlaps with other 14-bit SAR ADCs if cross-referencing is required.
