Optimized for high dynamic performance and ultra-low power, the device integrates a dual 10-bit, 7.5Msps receive (Rx) ADC; dual 10-bit, 7.5Msps transmit (Tx) DAC; three fast-settling 12-bit aux-DAC channels for ancillary RF front-end control; and a 10-bit, 333ksps housekeeping aux-ADC. The typical operating power in FD mode is 30mW at a 7.5MHz clock frequency. The Rx ADCs feature 54.8dB SINAD and 79.8dBc SFDR at 3.3MHz i...
