LTC1403CMSE#PBF

Analog To Digital Converters (ADC) Overview

The LTC1403CMSE#PBF is a 12-bit, 2.8Msps serial analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 10-lead MSOP package. It operates on a single 3V supply, drawing 4.7mA in active mode with power dissipation of 12mW. The device features differential inputs supporting a 0V to 2.5V unipolar range and includes an internal 2.5V bandgap reference. Key performance metrics include a full power bandwidth of 50MHz, 80dB common mode rejection ratio (CMRR), and a 3-wire serial interface. It supports Sleep (10µW) and Nap (3mW) shutdown modes for portable applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates tube packaging for the commercial grade (C) variant. Confirm the temperature range is 0°C to 70°C. Ensure the ordering part number matches the required resolution (LTC1403 for 12-bit vs LTC1403A for 14-bit). Check lead-free compliance status as per manufacturer documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for high-speed, low-power applications requiring differential input processing. The 12-bit resolution suits general-purpose data acquisition where 14-bit precision (LTC1403A) is unnecessary. Ensure the driving circuit can settle within the 39ns acquisition time if source impedance is high. Verify that the 3-wire serial interface timing meets system clock requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1403 family, which also includes the 14-bit LTC1403A variant. The 'CMSE' designation specifies the commercial temperature range (0°C to 70°C) and the 10-lead MSOP plastic package. The '#PBF' suffix denotes a lead-free finish and tube shipping configuration.
