MAX19711ETN+T

The MAX19711 is an ultra-low-power, highly integrated mixed-signal analog front-end (AFE) ideal for CDMA communication applications operating in full-duplex (FD) mode. Optimized for high dynamic performance and ultra-low power, the device integrates a dual 10-bit, 11Msps receive (Rx) ADC; dual 10-bit, 11Msps transmit (Tx) DAC with CDMA baseband filters; 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 37.5mW/42.7mW at a 4.915MHz/11MHz clock frequency.
