LTC1403HMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1403HMSE#TRPBF 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 with a typical active current of 5.2mA and power dissipation of 14mW. 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 Signal-to-Noise Plus Distortion Ratio (SINAD) of 70.5dB at 1.4MHz input and a Spurious Free Dynamic Range (SFDR) of -83dB. It offers Sleep (10µW) and Nap (3mW) shutdown modes for low-power applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the 'H' grade designation ensures operation within the –40°C to 125°C temperature range. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct pinout configuration.

Analog To Digital Converters (ADC) Selection Notes

Select this component for high-speed, portable applications requiring low power consumption. Ensure the input signal fits the 0V to 2.5V differential range. Verify that the driving circuit can settle within the 39ns acquisition time if source impedance is high. Consider the external reference voltage requirements if overdriving the internal VREF pin.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1403/LTC1403A family of serial sampling ADCs. The 'H' suffix denotes the industrial/extended temperature grade (-40°C to 125°C), while 'MSE' specifies the 10-lead MSOP package. The '#TRPBF' suffix confirms lead-free finish and tape-and-reel shipping format.
