LTC1403CMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1403CMSE#TRPBF is a 12-bit, 2.8Msps serial sampling analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 10-lead MSOP package. It operates on a single 3V supply with active power dissipation of 12mW and features a Sleep shutdown mode reducing consumption to 10µW. The device utilizes a successive approximation register (SAR) architecture with differential inputs supporting a 0V to 2.5V unipolar range. Key electrical specifications include a full power bandwidth of 50MHz, an internal 2.5V bandgap reference, and a 3-wire serial interface compatible with standard digital logic levels.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 2.8Msps maximum sampling rate
• Low power operation: 12mW active, 10µW Sleep mode
• Differential inputs with 80dB common mode rejection ratio
• Integrated 2.5V internal reference with overdrive capability

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 rather than tube packaging. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure compatibility with the 10-lead MSOP footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed conversion with minimal power consumption. The 12-bit resolution suits general-purpose data acquisition where 14-bit precision (LTC1403A) is unnecessary. Verify that the driving source impedance allows for the specified 39ns acquisition time without external buffering.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1403 family, which includes the higher-resolution LTC1403A variant offering 14-bit performance. The CMSE#TRPBF designation specifically identifies the commercial temperature grade version supplied in tape and reel format for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1403IMSE#TRPBF serves as a direct replacement for industrial temperature range requirements (-40°C to 85°C). For applications necessitating higher resolution, the LTC1403A series provides 14-bit accuracy within the same package and pinout configuration.
