General Description
The MAX19707 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, 45Msps receive (Rx) ADC; dual, 10-bit,45Msps 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 84.6mW at a 45MHz clock frequency.
The Rx ADCs feature 54.2dB SNR and 71.2dBc SFDRat fIN = 5.5MHz and fCLK= 45MHz. The analog I/Q input amplifiers are fully differential and accept 1.024VP-Pfull-scale signals. Typical I/Q channel matching is ±0.03° phase and ±0.01dB gain.
