LTC2480CMS#PBF

The LTC2480CMS#PBF is a 16-bit plus sign No Latency Delta Sigma analog-to-digital converter from Linear Technology (LT) that incorporates patented Easy Drive technology. This technology eliminates dynamic input current errors and the limitations of on-chip buffering by automatically canceling differential input current. This allows for direct digitization of input signals with rail-to-rail input range and large external source impedances while maintaining exceptional DC accuracy.

Key electrical specifications include a 16-bit resolution, a Delta Sigma architecture, and a unipolar input type. It supports a programmable gain from 1 to 256 and operates over a wide supply voltage range of 2.7V to 5.5V. The device features a low power consumption of 0.48 mW and a selectable 2x speed mode, achieving a sampling rate of 15 Hz using its internal oscillator. It offers excellent accuracy with an INL of 2 ppm and an offset error of 1 ppm.

The LTC2480CMS#PBF is designed for applications requiring direct sensor digitization, such as weight scales. It features a programmable 50Hz, 60Hz, or simultaneous 50Hz/60Hz rejection mode and no latency, as the digital filter settles in a single cycle. The device is available in a compact 3mm x 3mm 10-lead DFN package, suitable for surface mount applications.
