LTC2508-32 Image

The LTC2508-32 is a low noise, low power, 32-bit ADC with an integrated configurable digital filter. The digital filter can be easily configured for 4 different down-sampling factors by pin strapping. The configurations provide a dynamic range of 131 dB at 3.9ksps and 145 dB at 61sps. The ADC has a fully differential input range from 2.5V to 5.1V. It simultaneously provides two output codes: (1) a 32-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 32-bit filtered output code. The 22-bit composite code consists of a 14-bit code representing the differential voltage and an 8-bit code representing the common mode voltage. The 22-bit composite code is available each conversion cycle, with no cycle of latency. It is available in a 24-Lead 7 x 4 mm DFN Package and is ideal for seismology, energy exploration and automated test equipment applications.
