Power-Down Lockout Input (
PDL
)
The power-down lockout pin (
PDL
) disables shutdown
when low. When in shutdown mode, a high-to-low tran-
sition on
PDL
will wake up the DAC with its output still
set to the state prior to power-down.
PDL
can also be
used to wake up the device asynchronously.
Power-Down Input (PD)
Pulling PD high places the MAX5120/MAX5121 in shut-
down mode. Pulling PD low will not return the MAX5120/
MAX5121 to normal operation. A high-to-low transition
on
PDL
or appropriate commands (Table 1) via the seri-
al interface are required to exit power-down.
S erial-Interfac e Configuration
(S PI/QS PI/MICROWIRE/PIC16/PIC17)
The MAX5120/MAX5121 3-wire serial interface is com-
patible with SPI, QSPI, PIC16/PIC17 (Figure 4) and
MICROWIRE (Figure 5) interface standards. The 2-byte-
long serial input word contains three control bits, 12 data
bits in MSB-first format and one sub-bit, which is always
zero (Table 2).
The MAX5120/MAX5121’s digital inputs are double
buffered, which allows the user to:
Load the input register without updating the DAC
register;
Update the DAC register with data from the input
register;
Update the input and DAC registers concurrently.
