Description:
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 frequency.
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-Pfull-scale signals. Typical I/Q channel matching is ±0.12° phase and ±0.01dB gain.

5. Three 12-Bit, 1µs Aux-DACs
6. 10-Bit, 333ksps Aux-ADC with 4:1 Input Mux and Data Averaging Mode
7. Excellent Gain/Phase Match ±0.12° Phase, ±0.01dB Gain (Rx ADC) at fIN = 5.5MHz
8. Multiplexed Parallel Digital I/O
9. Serial-Interface Control
10. Versatile Power-Control Circuits Shutdown, Standby, Idle, Tx/Rx Disable
11. Miniature 48-Pin Thin QFN Package (7mm x 7mm x 0.8mm)
