Table 5. MAX19711 Tx, Rx, and FD Control Using SPI Commands
Shutdown mode offers the most dramatic power sav-
ings by shutting down all the analog sections (including
the reference) of the MAX19711. In shutdown mode,
the Rx ADC digital outputs are in tri-state mode, the Tx
DAC digital inputs are internally pulled to OVDD, and
the Tx DAC outputs are at 0V. When the Rx ADC out-
puts transition from tri-state to active mode, the last
converted word is placed on the digital output bus. The
Tx DAC previously stored data is lost when coming out
of shutdown mode. The wake-up time from shutdown
mode is dominated by the time required to charge the
capacitors at REFP, REFN, and COM. In internal refer-
ence mode and buffered external reference mode, the
wake-up time is typically 500s to enter Rx mode, 26s
to enter Tx mode, and 500s to enter FD mode.
In all operating modes the Tx DAC inputs DA0–DA9 are
internally pulled to OVDD. To reduce the supply current
of the MAX19711 in shutdown mode do not pull
DA0–DA9 low. This consideration is especially impor-
tant in shutdown mode to achieve the lowest quiescent
current.
In idle mode, the reference and clock distribution cir-
cuits are powered, but all other functions are off. The
