LTC1403CMSE-1#PBF

Analog To Digital Converters (ADC) Overview

The LTC1403CMSE-1#PBF is a 12-bit, 2.8Msps serial sampling analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 3V supply and features differential inputs with a ±1.25V bipolar range. The device integrates a 2.5V internal bandgap reference and offers low power consumption of 14mW in active mode, with Sleep and Nap shutdown modes reducing dissipation to 10µW and 3mW respectively. Housed in a 10-lead MSOP package, it utilizes a 3-wire serial interface for data output.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 2.8Msps sampling rate
• Single 3V supply operation with 14mW active power dissipation
• Integrated 2.5V internal reference with Sleep (10µW) and Nap (3mW) shutdown modes
• Differential inputs with 80dB common mode rejection

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 and RoHS compliance when sourcing. Confirm the CMSE variant corresponds to the commercial temperature range (0°C to 70°C). Ensure the ordering code matches the required tube packaging format rather than tape and reel options.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed conversion within a tight power budget. The 12-bit resolution distinguishes it from the 14-bit LTC1403A-1 variant. Designers must account for the 2ms reference settling time when transitioning from Sleep mode. The serial interface requires careful timing management to achieve the maximum throughput rate.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1403-1/LTC1403A-1 family of serial SAR ADCs. The 'C' designation specifies the commercial operating temperature range of 0°C to 70°C, while 'I' denotes industrial range (-40°C to 85°C). The MSE package refers to the 10-lead plastic MSOP form factor with an exposed ground pad.
