n Low Power Instrumentation n Software-Defined Radios n Portable Medical Imaging n Multi-Channel Data Acquisition LTC2271 16-Bit, 20Msps Serial Low Noise Dual ADC DESCRIPTION
DC specs include ±1LSB INL (typ), ±0.2LSB DNL (typ) and no missing codes over temperature. The transition noise is 1.44LSBRMS. To minimize the number of data lines the digital outputs are serial LVDS. Each channel outputs one bit, two bits or four bits at a time. The LVDS drivers have optional internal termination and adjustable output levels to ensure clean signal integrity.
