LTC1403CMSE-1#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1403CMSE-1#TRPBF is a 12-bit, 2.8Msps successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 3V supply and features a 3-wire serial interface with differential inputs. The device includes an internal 2.5V bandgap reference and offers low power consumption of 14mW in active mode, with Sleep (10µW) and Nap (3mW) shutdown modes. It is housed in a 10-lead MSOP package with an exposed pad for thermal grounding.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 2.8Msps sampling rate
• Differential input range of ±1.25V with 80dB CMRR
• Internal 2.5V reference; Sleep/Nap shutdown modes
• 3-wire serial interface compatible with standard logic levels

Analog To Digital Converters (ADC) Applications

• Data acquisition systems
• Multiphase motor control
• Uninterrupted power supplies
• Multiplexed data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube. Confirm the 'C' grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the source document explicitly lists this part number as available from the manufacturer or authorized distributors.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1403A-1 variant if 14-bit resolution is required instead of the 12-bit LTC1403-1. Consider the IMSE suffix for industrial temperature ranges (-40°C to 85°C). Verify that the 50MHz full power bandwidth meets the signal frequency requirements for the specific application.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1403-1/LTC1403A-1 family of high-speed, low-power SAR ADCs. The CMSE-1 designation specifies the 12-bit version in a 10-lead MSE package with commercial temperature rating. The #TRPBF suffix denotes lead-free tape and reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the LTC1403IMSE-1#TRPBF for industrial temperature operation and the LTC1403ACMSE-1#TRPBF for commercial temperature with potential performance variations.
