The MAX19713ETN+ is a 10bit, 45Msps, full duplex analogue front-end in 56 pin TQFN package. It is optimized for high dynamic performance and ultralow power, the device integrates a dual 10bit, 45Msps receive (Rx) ADC, dual 10bit, 45Msps transmit (Tx) DAC & three fast-settling 12bit aux-DAC channels for ancillary RF front-end control and a 10bit, 333Ksps housekeeping aux-ADC. The typical operating power in FD mode is 91.8mW at a 45MHz clock frequency. The Rx ADC feature 54dB SINAD and 72.2dBc SFDR at 5.5MHz input frequency with a 45MHz clock frequency and the Tx DAC feature 70.3dBc SFDR at fOUT = 2.2MHz and fCLK = 45MHz. The Rx ADC and Tx DAC can be disabled independently to optimize power management. It is used in WiMAX CPEs, 801.11a/b/g WLAN and VoIP terminals.
