LTC1403ACMSE-1#PBF

Analog To Digital Converters (ADC) Overview

The LTC1403ACMSE-1#PBF 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 4.7mA in active mode and consuming only 10µW in Sleep shutdown mode. The device features a ±1.25V bipolar differential input range, an internal 2.5V bandgap reference, and a 3-wire serial interface. Key performance metrics include 80dB common mode rejection at 1MHz and a typical SINAD of 70.5dB at 100kHz input frequency.

Analog To Digital Converters (ADC) Feature Summary

• 14-bit resolution with 2.8Msps sampling rate
• Ultra-low power consumption: 14mW active, 10µW Sleep mode
• Internal 2.5V reference with overdrive capability up to VDD
• Differential inputs supporting 0V to VDD common mode range

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the AC grade designation ensures operation within the 0°C to 70°C commercial temperature range. Check for availability of the tape and reel variant (#TRPBF) if automated surface-mount assembly is required instead of tube packaging.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 14-bit precision is required alongside high-speed conversion. The AC grade is suitable for standard commercial environments. Ensure the driving circuit can settle within the 39ns acquisition time to maintain full throughput. Consider the external reference option if higher linearity or different voltage spans are needed beyond the internal 2.5V limit.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1403-1/LTC1403A-1 family, which offers both 12-bit (LTC1403-1) and 14-bit (LTC1403A-1) resolutions. The ACMSE-1 variant specifically denotes the commercial temperature range version in the MSE package. It shares architectural similarities with other low-power SAR ADCs but distinguishes itself through its tiny footprint and deep sleep capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the LTC1403IMSE-1#PBF for extended industrial temperature ranges (-40°C to 85°C). The LTC1403CMSE-1#PBF serves as a direct replacement if 12-bit resolution is sufficient for the application.
