LTC2411-1CMS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2411-1CMS#TRPBF is a 24-bit differential delta-sigma analog-to-digital converter in a 10-lead MSOP package. It operates on a single supply of 2.7V to 5.5V and features an integrated oscillator with no latency. The device provides simultaneous 50Hz/60Hz rejection over the range of 49Hz to 61.2Hz, achieving better than 87dB input differential mode rejection. Key electrical parameters include 2ppm integral nonlinearity (INL), 0.29ppm RMS noise, and 200µA supply current in conversion mode. It communicates via a flexible 3-wire digital interface compatible with SPI and MICROWIRE protocols.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'C' designation corresponds to the commercial temperature range of 0°C to 70°C as specified in the manufacturer's order information table. Ensure the source document matches the Analog Devices datasheet 2411fa for accurate pinout and electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2411-1 variant specifically when simultaneous rejection of both 50Hz and 60Hz line frequencies is required within the 49Hz to 61.2Hz range. Choose the CMS package version for commercial temperature operation (0°C to 70°C). This component is suitable for applications requiring high precision without external clock components or complex configuration registers.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2411 family of 24-bit ADCs manufactured by Analog Devices. The LTC2411-1 variant is distinct from the standard LTC2411 by its ability to reject both 50Hz and 60Hz interference simultaneously. The CMS#TRPBF designation identifies the commercial grade, MSOP-10 package, and tape-and-reel delivery format.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify compatibility with existing circuit designs if considering alternative delta-sigma ADCs, as the specific notch filter characteristics and pin configurations may differ.
