Detailed Description

High-precision delta-sigma analog-to-digital converter from the LTC24xx family (formerly Linear Technology, now ADI), with an I2C-compatible digital interface. Designed for simple integration, low noise, and precision measurements. Supports differential sensing, strong rejection of 50 Hz and 60 Hz mains interference, very low power operation, and easy single-shot conversions with no complicated setup. Ideal for sensors and instruments that need stable, accurate readings and low drift over time.

Key Features

Delta-sigma ADC architecture for high resolution and low noise

I2C serial interface for simple two-wire control and data readout

Differential input capability for improved common-mode noise rejection

Strong 50 Hz and 60 Hz rejection for cleaner measurements in real-world environments

Single-shot and continuous conversion modes for flexible operation

Internal oscillator for hassle-free timing (no external clock needed)

Low power consumption suitable for battery-powered systems

Wide supply compatibility typical of LTC24xx family devices

Family ecosystem compatibility for design reuse and easy migration

RoHS lead-free version indicated by the #PBF suffix

Key Advantages

Easy to design in: minimal external components, straightforward I2C control

Accurate and stable readings: delta-sigma conversion with mains noise rejection

Compact solution size: small DFN footprint fits tight layouts

Low power draw: extends battery life and reduces self-heating

Scalable family: drop-in alternatives available for different resolutions or interfaces

Proven reliability: ADI’s industrial-grade analog performance and quality

Packaging

Type: 8-lead DFN (ADI/LT package code CDD), lead-free #PBF

Material: Molded plastic DFN with copper leadframe

Size: Compact low-profile DFN footprint, approximately 3 mm x 2 mm body

Case reference: Our catalog case code 1288

Pin configuration (typical for this family): VCC, GND, SDA, SCL, differential analog inputs (IN+, IN−), reference pins (REF+, REF− or REFIN). Check the datasheet for the exact pinout of LTC2480CDD.

Mounting: Surface-mount, compatible with automated pick-and-place and reflow

Supply forms: Tube/Tray for CDD #PBF and Tape-and-Reel for CDD #TRPBF (verify ordering codes)

Thermal characteristics: Very low self-heating due to low current; DFN package improves heat transfer to PCB copper planes. Follow JEDEC reflow profiles and use good layout for heat spreading.

Electrical properties (typical family behavior): Operates from a wide supply range commonly around 2.7 V to 5.5 V; input range set by reference; conversion times optimized for precision. Exact values in datasheet.

Lifecycle

Current status: Active and widely supported by ADI. Not approaching discontinuation based on typical market status for LTC24xx family devices.

Close family alternatives and equivalents for different needs:

- LTC2481: Similar I2C delta-sigma ADC option with related features

- LTC2482: I2C delta-sigma ADC variant; check resolution and input config

- LTC2484: Higher-resolution I2C delta-sigma ADC option in the same family

- LTC2460 / LTC2461: Low-power 16-bit delta-sigma ADCs with I2C interface

- LTC2450 / LTC2451: Ultra-low-power 16-bit I2C delta-sigma ADCs for simple sensors

These are alternatives depending on resolution, input type (single-ended vs differential), speed, and power. Review the datasheets or contact us to select the best fit.
