LTC2470CDD#PBF

Analog To Digital Converters (ADC) Overview

The LTC2470CDD#PBF is a 16-bit delta-sigma analog-to-digital converter (ADC) from Analog Devices, housed in a 12-lead 3mm × 3mm DFN package. It features an integrated precision reference with 10ppm/°C maximum drift and offers selectable output rates of 208sps or 833sps. The device operates on a single 2.7V to 5.5V supply and communicates via an SPI interface. Key electrical characteristics include a typical supply current of 3.5mA during conversion and a maximum sleep current of 2µA. It provides 16-bit resolution with ±1mV offset error and ±0.01% gain error, designed for low-power multiplexed applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing components. Confirm the C-grade designation ensures the 0°C to 70°C operating temperature range required for the application. Cross-reference the manufacturer part number with official distributor catalogs to ensure authenticity and correct lead-free finish specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2470 variant for single-ended input applications requiring a 0V to VREF range. Choose the C-grade version for commercial temperature ranges (0°C to 70°C). Ensure the system design accommodates the 3mm × 3mm DFN package footprint and thermal requirements. Verify that the SPI interface timing matches the host controller's capabilities for reliable data transfer.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2470/LTC2472 family of high-precision, low-power ADCs. The LTC2470 is distinguished by its single-ended input architecture, whereas the LTC2472 supports differential inputs. Both share identical pinouts, power management features, and internal reference specifications, allowing for flexible design choices based on input signal requirements.
