Maxim Integrated MAX19711ETN T

Description
The MAX19711 is an ultra-low-power, highly integrated mixed-signal analog front-end (AFE) designed for CDMA communication applications operating in full-duplex (FD) mode. It 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.
