LTC2380IDE-24#PBF

LINEAR TECHNOLOGY  LTC2380IDE-24#PBF  模数转换器, 低功率SAR, 24 bit, 2 MSPS, 单, 2.375 V, 2.625 V, DFN

The is a 24bit low power SAR analogue to digital converter ADC with integrated digital filter in 16 pin DFN package. This low noise, high speed ADC operates from single 2.5V supply and has ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2380-24 consumes only 28mW and achieves ±3.5ppm INL maximum with no missing codes at 24bits. The device has an easy to use integrated digital averaging filter that can average 1 to 65536 conversion results in real time which dramatically improves dynamic range from 101dB at 1.5MSPS to 145dB at 30.5sps. It does not require separate programming interface or configuration register. The high speed SPI compatible serial interface supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring daisy chain mode. The LTC2380-24 automatically powers down between conversions by reducing power dissipation at lower sampling rates.
