LTC1403AHMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1403AHMSE#TRPBF is a 14-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 active power dissipation of 14mW and features a Sleep shutdown mode reducing consumption to 10µW. The device utilizes a SAR architecture with differential inputs supporting a 0V to 2.5V unipolar range and an internal 2.5V bandgap reference. Key performance metrics include a typical SINAD of 70.5dB at 1.4MHz input and an SFDR of 90dB. It guarantees operation over the -40°C to 125°C temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the AH grade designation corresponds to the extended -40°C to 125°C operating temperature range required for the application environment. Cross-reference the manufacturer part number with official distributor catalogs to ensure authenticity and correct lot traceability.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1403A variant specifically for applications requiring 14-bit resolution; the standard LTC1403 provides only 12 bits. Ensure the driving circuit can settle within the 39ns acquisition time if high source impedance is present. Verify that the system clock frequency supports the required throughput without violating the minimum pulse width constraints for SCK and CONV signals.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1403 family of high-speed, low-power serial ADCs. The 'H' suffix denotes the extended temperature grade (-40°C to 125°C), while 'A' specifies the 14-bit resolution version. The 'MS' indicates the 10-lead plastic MSOP package, and '#TRPBF' confirms lead-free tape and reel packaging suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1403IMSE#TRPBF serves as a direct functional substitute if the application does not require the extended -40°C to 125°C temperature range, offering the same 14-bit resolution and electrical characteristics within the commercial 0°C to 70°C limit.
