LINEAR TECHNOLOGY  LTC2389IUK-18#PBF  模数转换器, 18 bit, 2.5 MSPS, 单, 4.75 V, 5.25 V, QFN

The is a low noise, high speed successive approximation registers Analog-to-digital Converter ADC. Operating from a single 5V supply, the ADC supports pin configurable fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges, allowing it to interface with multiple signal chain formats without requiring additional level translation or signal conditioning. The ADC includes a precision internal 4.096V reference with a guaranteed 0.5% initial accuracy and a ±20ppm/°C temperature coefficient, as well as an internal reference buffer. Fast 2.5Msps throughput with no cycle latency in the parallel interface modes makes the ADC ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The ADC dissipates only 162.5mW at 2.5Msps, while both nap and sleep power-down modes are provided to further reduce power consumption during inactive periods.
