LTC2512CDKD-24#PBF

LTC2512-24 is a low noise, low power, high-performance 24bit ADC with an integrated configurable digital filter. It features a fully differential input range upto ±VREF, with VREF ranging from 2.5V to 5.1V. It supports a wide common mode range from 0V to VREF simplifying analogue signal conditioning requirements. It simultaneously provides two output codes: (1) a 24-bit digitally filtered high precision low noise code, and (2) a 22-bit no latency composite code. The configurable digital filter reduces measurement noise by lowpass filtering and down-sampling the stream of data from the SAR ADC core, giving the 24-bit filtered output code. The 22-bit composite code consists of a 14bit code representing the differential voltage and an 8-bit code representing the common mode voltage. It is used in applications such as seismology, energy exploration, automated test equipment (ATE), high-accuracy instrumentation.
