Analog To Digital Converters (ADC) datasheet and documents for LTC2446IUHF#PBF

LTC2446IUHF#PBF

Analog To Digital Converters (ADC) Overview

The LTC2446IUHF#PBF is a 24-bit, 8-channel delta-sigma analog-to-digital converter (ADC) from Analog Devices Inc. It features selectable multiple differential reference inputs and supports up to 8kHz output rates with an external clock. The device offers noise performance as low as 200nV RMS at 13.8Hz with simultaneous 50/60Hz rejection. It operates on a single 4.5V to 5.5V supply, consumes 8mA during conversion, and includes autosleep functionality for 20µA standby current. The component is housed in a 38-lead 5mm × 7mm plastic QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging. Confirm the 'I' grade designation corresponds to the –40°C to +85°C operating temperature range. Ensure the source documentation matches the 38-lead QFN physical dimensions and pinout configuration provided in the official datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this model when high channel count and multi-reference capability are required. The LTC2446 differs from the LTC2447 by lacking MUXOUT/ADCIN pins for external buffering. Choose based on the need for ratiometric sensing versus absolute voltage measurement requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2446/LTC2447 family of high-speed delta-sigma ADCs. It shares architectural similarities with other Linear Technology precision converters but is distinct in its integrated multiplexer and flexible reference input structure designed for multi-sensor applications.
