LTC2500IDKD-32#PBF

LTC®2500-32 is a low-noise, low-power, high-performance 32-bit ADC with an integrated configurable digital filter. Operating from a single 2.5V supply, the LTC2500-32 features a fully differential input range up to ±VREF with VREF ranging from 2.5V to 5.1V. The LTC2500-32 supports a wide common mode range from 0V to VREF simplifying analogue signal conditioning requirements. LTC2500-32 simultaneously provides two output codes: (1) a 32-bit digitally filtered high-precision low noise code and (2) a 32-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 32-bit filtered output code. Typical applications include Seismology, energy exploration, automatic test equipment and high accuracy instrumentation.
