LTC2368IDE-24#PBF

The LTC2368IDE-24#PBF is a 24bit, 1Msps, pseudo differential unipolar SAR ADC with integrated digital filter in 16 pin DFN package. This low noise, low power, high speed 24bit SAR ADC with an integrated digital averaging filter operates from a 2.5V supply and has a 0V to VREF pseudo differential unipolar input range with VREF ranging from 2.5V to 5.1V. The LTC2368-24 consumes only 21mW (typ) and achieves ±4.5ppm INL maximum and no missing codes at 24bits. It has an easy to use integrated digital averaging filter that can average 1 to 65536 conversion results real-time, dramatically improving dynamic range from 98dB at 1Msps to 140dB at 15.25sps. The high speed SPI-compatible serial interface supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy chain mode. It automatically powers down between conversions, reducing power dissipation at lower sampling rates. It is used in seismology, energy exploration, medical imaging, high speed data acquisition and ATE.
