LTC2482IDD#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2482IDD#TRPBF is a 16-bit delta-sigma analog-to-digital converter featuring patented Easy Drive technology for automatic differential input current cancellation. It operates on a single supply voltage ranging from 2.7V to 5.5V and supports reference voltages as low as 100mV. The device achieves 2ppm integral nonlinearity with no missing codes and includes an internal oscillator providing simultaneous 50Hz/60Hz rejection. It utilizes a 3-wire SPI interface and is housed in a compact 10-lead 3mm x 3mm DFN package.

Analog To Digital Converters (ADC) Feature Summary

• Patented Easy Drive technology eliminates dynamic input current errors, enabling direct digitization of high impedance sensors without external amplifiers.
• 16-bit resolution with 2ppm INL, 1ppm offset error, and 15ppm total unadjusted error.
• Internal oscillator provides 87dB rejection of 50Hz and 60Hz line frequency noise.
• Rail-to-rail input common mode range (GND to VCC) independent of the reference voltage.

Analog To Digital Converters (ADC) Applications

• Direct sensor digitizer
• Weight scales
• Strain gauge transducers
• Industrial process control
• DVMs and meters

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the IDD suffix corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the 10-lead DFN package dimensions for PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high accuracy is required with minimal external circuitry due to the Easy Drive feature. The internal oscillator simplifies design by removing the need for external crystals. Ensure the application requires a 3-wire serial interface and fits within the 2.7V to 5.5V supply constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2482 family of 16-bit ADCs. The IDD variant specifies the industrial temperature grade (-40°C to +85°C), distinguishing it from the CDD variant which covers the commercial range (0°C to 70°C). Both share identical electrical specifications and pinouts.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2482CDD#TRPBF is a compatible alternative if the commercial temperature range (0°C to 70°C) suffices for the application. Other parts in the series like LTC2481 or LTC2483 offer similar features but may differ in channel count or specific interface configurations.
