LTC2408CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2408CG#TRPBF is an 8-channel, 24-bit micropower delta-sigma analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single supply voltage ranging from 2.7V to 5.5V and features an integrated oscillator with no latency delay, ensuring the first conversion after channel switching is valid. Key electrical specifications include 4ppm integral nonlinearity (INL), 0.3ppm RMS noise, and a minimum of 110dB rejection at 50Hz or 60Hz. The device accepts external reference voltages from 0.1V to VCC and provides an extended input range of –12.5% to 112.5% VREF. It communicates via a flexible 4-wire digital interface compatible with SPI and MICROWIRE protocols.

Analog To Digital Converters (ADC) Feature Summary

• 24-bit resolution with 4ppm INL and 0.3ppm RMS noise
• 8-channel analog multiplexer with single-cycle settling time
• Integrated oscillator providing >110dB rejection at 50Hz/60Hz
• Extended input range: –0.125•VREF to 1.125•VREF

Analog To Digital Converters (ADC) Applications

• Weight scales
• Direct temperature measurement
• Gas analyzers
• Strain gauge transducers
• Instrumentation and data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type is 28-lead SSOP and the operating temperature range is commercial (0°C to 70°C). Confirm the suffix #TRPBF indicates tape and reel packaging. Ensure the source document matches the official Analog Devices datasheet for the LTC2404/LTC2408 family to validate pinout and electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2408 over the LTC2404 when eight analog inputs are required, as the LTC2404 only supports four channels. Both devices share identical electrical performance and pinouts for the active channels. Ensure the application requires a single-ended input configuration, as this device does not support differential inputs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2404/LTC2408 family of micropower, no-latency delta-sigma ADCs. The 'C' in the part number denotes the commercial temperature grade (0°C to 70°C), while 'I' would indicate industrial grade (-40°C to 85°C). The '#TRPBF' suffix specifies the reel packaging and lead-free compliance.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2404IG#TRPBF is a pin-compatible alternative if only four channels are needed. For industrial temperature ranges, the LTC2408IG#TRPBF offers the same functionality with a -40°C to 85°C operating range.
