LTC2463CDD#PBF

Analog To Digital Converters (ADC) Overview

The LTC2463CDD#PBF is a 16-bit analog-to-digital converter featuring a differential input architecture and an integrated precision reference. It operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a 2-wire I²C interface. The device includes a 1.25V internal reference with a maximum drift of 10ppm/°C for the C-grade variant. Key electrical parameters include a typical supply current of 1.5mA during conversion, reduced to 200nA in sleep mode. The component supports data rates up to 60 conversions per second and utilizes a proprietary sampling scheme to minimize average input current.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package type and temperature grade when ordering. The suffix 'CDD' indicates a 12-lead plastic DFN package with a commercial operating temperature range of 0°C to 70°C. Ensure compatibility with the required I²C bus speed and voltage levels before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2463CDD#PBF for applications requiring differential inputs and low power consumption. The C-grade variant is suitable for commercial environments within the 0°C to 70°C range. For industrial temperatures (-40°C to 85°C), consider the IDD suffix. Ensure external filtering components are selected to maintain the specified noise performance given the 50nA average input sampling current.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2461/LTC2463 family of ultra-tiny delta-sigma ADCs. While the LTC2461 offers single-ended inputs, the LTC2463 provides differential inputs for improved noise rejection. Both share pinout compatibility and software control protocols, allowing for flexible design choices based on input signal requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical specifications if considering alternative manufacturers for similar 16-bit I²C ADCs.
