General Description
The MAX19705 is an ultra-low-power, mixed-signal ana-
log front-end (AFE) designed for power-sensitive com-
munication equipment. Optimized for high dynamic
performance at ultra-low power, the device integrates a
dual 10-bit, 7.5Msps receive (Rx) ADC; dual 10-bit,
7.5Msps 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 typ-
ical operating power in Tx-Rx FAST mode is 28.2mW at
a 7.5MHz clock frequency.
The Rx ADCs feature 55.1dB SNR and 73.4dBc SFDR at
a 1.875MHz input frequency with a 7.5MHz clock fre-
quency. The analog I/Q input amplifiers are fully differen-
tial and accept 1.024VP-P full-scale signals. Typical I/Q
channel matching is ±0.01° phase and ±0.02dB gain.
The Tx DACs feature 77.2dBc SFDR at fOUT = 620kHz
and fCLK = 7.5MHz. 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 ±0.03dB gain and ±0.08° 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 MAX19705 operates on a single +2.7V to +3.3V
analog supply and +1.8V to +3.3V digital I/O supply.
The MAX19705 is specified for the extended (-40°C to
+85°C) temperature range and is available in a 48-pin,
thin QFN package. The Selector Guide at the end of the
data sheet lists other pin-compatible versions in this
AFE family.
