LTC1407AHMSE#PBF

Analog To Digital Converters (ADC) Overview

The LTC1407AHMSE#PBF is a 14-bit, 3Msps simultaneous sampling analog-to-digital converter (ADC) from Analog Devices. It features two differential inputs sampled at 1.5Msps per channel on the rising edge of the CONV signal. Operating from a single 3V supply, it draws 4.7mA in active mode and dissipates 12mW typical power. The device includes an internal 2.5V bandgap reference, a 3-wire serial interface, and Sleep/Nap shutdown modes reducing consumption to 10μW/3mW. It utilizes a 10-lead MSOP package with an exposed ground pad.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade suffix 'H' indicates operation from -40°C to +125°C. Confirm the '#PBF' suffix denotes lead-free finish and RoHS compliance. Ensure the ordering code matches the required tape and reel or tube packaging format specified in the manufacturer's documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel simultaneous sampling is required at high speeds with low power constraints. The 14-bit resolution suits applications needing higher precision than the 12-bit variant. Verify that the 0V to 2.5V unipolar input range aligns with the source signal levels and that the 3V single-supply architecture fits the system design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1407/LTC1407A family of serial ADCs. The 'AH' designation specifies the industrial/high-temperature grade (-40°C to +125°C), while the 'A' suffix indicates 14-bit resolution. It shares the same pinout and core architecture as the 12-bit LTC1407 variants but offers enhanced resolution for demanding signal processing tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same package include other LTC1407 variants with different temperature grades or resolutions, such as the LTC1407AIMSE#PBF (14-bit, -40°C to 85°C). Cross-family replacements require verifying pin compatibility and electrical parameter alignment.
