MAX19706 10-Bit, 22Msps, Ultra-Low-Power Analog Front-End

The MAX19706 is an ultra-low-power, Mixed-Signal Analog front-end (AFE) designed for power-sensitive Communication equipment. Optimized for high dynamic performance at ultra-low power, the device integrates a dual, 10-bit, 22Msps receive (Rx) ADC; dual, 10-bit, 22Msps 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 Tx-Rx FAST mode is 49.5mW at a 22MHz Clock freq 4ff uency. The Rx ADCs feature 54.6dB SNR and 75.6dBc SFDR at a 5.5MHz input frequency with a 22MHz Clock frequency. The Analog I/Q input Amplifiers are fully differential and accept 1.024VP-P full-scale signals. Typical I/Q channel matching is 0.12 phase and 0.01dB gain. The Tx DACs feature 72.6dBc SFDR at fOUT = 2.2MHz and fCLK = 22MHz. The Analog I/Q full-scale output voltage is 400mV differential. The Tx DAC common-mode DC level is programmable from 0.9V to 1.35V. The I/Q channel offset is adjustable. The typical I/Q channel matching is 0.02dB gain and 0.1 phase. The Rx ADC and Tx DAC share a single, 10-bit parallel, high-speed digital bus allowing half-duplex operation for time-division duplex (TDD) applications. A 3-wire serial Interface controls power-management modes, the aux-DAC channels, and the aux-ADC channels. The MAX19706 operates on a single +2.7V to +3.3V Analog supply and +1.8V to +3.3V digital I/O supply. The MAX19706 is specified for the extended (-40C to +85C) temperature range and is available in a 48-pin, thin QFN package. See a parametric table of the complete family of pin-compatible AFEs.
