LTC2484IDD#PBF

The LTC2484IDD#PBF is a 24-bit No Latency Delta-Sigma analog-to-digital converter from Analog Devices, Inc., incorporating patented Easy Drive technology. This technology eliminates dynamic input current errors and on-chip buffering issues by automatically canceling differential input current. This allows for direct digitization of signals from high impedance sensors with rail-to-rail input range and exceptional DC accuracy.

Key electrical specifications include a 24-bit resolution, a sampling rate of 7.5 Sps, and a single differential input channel. It supports an SPI data interface and operates from a single supply voltage ranging from 2.7V to 5.5V. The device features programmable 50Hz, 60Hz, or simultaneous 50Hz/60Hz line frequency rejection, a selectable 2x speed mode, and an on-chip oscillator, eliminating the need for external crystals.

With 2ppm INL, 1ppm offset, and 15ppm total unadjusted error, the LTC2484IDD#PBF maintains high accuracy. It offers a wide GND to VCC input/reference common mode range and low noise of 600nVRMS. The device is available in a compact 10-lead DFN package measuring 3mm x 3mm, suitable for space-constrained applications.

Applications for the LTC2484IDD#PBF include direct sensor digitization, weight scales, direct temperature measurement, strain gauge transducers, instrumentation, industrial process control, and DVMs and meters.
