LTC2380CDE-24#PBF

LTC2380CDE-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 LTC2380-24 has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. 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 101dB at 1.5Msps to 145dB at 30.5sps. 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. The LTC2380-24 automatically powers down between conversions, reducing power dissipation at lower sampling rates. Applications include seismology, energy exploration, medical imaging, high speed data acquisition, industrial process control, and ATE.
