LTC2461IDD

Analog To Digital Converters (ADC) Overview

The LTC2461IDD is a 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features an integrated precision voltage reference and operates on a single supply voltage ranging from 2.7V to 5.5V. The device communicates via a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. It utilizes a proprietary input sampling scheme that significantly reduces average input current during power-down modes. The component is housed in a compact 10-lead DFN package and supports conversion rates up to 60 conversions per second.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IDD' against the manufacturer's official datasheet to confirm the package type and temperature range specifications. Ensure compatibility with system voltage levels and serial interface timing requirements before integration. Cross-reference part numbers with authorized distributors to confirm current availability status.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-resolution ADC performance with minimal external components due to the integrated reference. Consider the 16-bit resolution and 60Hz update rate for static or slow-varying signal measurements. Evaluate the power-down current characteristics if battery life is a critical constraint in the design.

Analog To Digital Converters (ADC) Part Context

The LTC2461 is part of the LTC246x family of ultra-tiny, 16-bit delta-sigma ADCs. This series includes variants such as the LTC2460 and LTC2462, which share similar core architectures but differ in input configurations and pin counts. The LTC2461 specifically offers a differential input configuration within a 10-lead DFN package.
