LTC2368IDE-24#PBF

LTC2368IDE-24#PBF is a low noise, low power, high-speed 24bit successive approximation register (SAR) ADC with an integrated digital averaging filter. Operating from a 2.5V supply, the LTC2368-24 has a 0V to VREF pseudo differential unipolar input range with VREF ranging from 2.5V to 5.1V. It consumes only 21mW(typ) and achieves ±4.5ppm INL maximum and no missing codes at 24 bits. It has an easy-to-use integrated digital averaging filter that can average 1 to 65536 conversion results in real-time, dramatically improving dynamic range from 98dB at 1Msps to 140dB at 15.25sps. No separate programming interface or configuration register is required. The high-speed SPI-compatible serial interface supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. Applications include seismology, energy exploration, medical imaging, high-speed data acquisition, industrial process control, and ATE.
