FORCE SENSE AMPLIFIER SELECTION
Use single-supply, low noise amplifiers. A low output impedance at
high frequencies is preferred because the amplifiers must be
able to handle dynamic currents of up to ±20 mA.
REFERENCE AND GROUND
Because the input impedance is code dependent, drive the refer-
ence pin from a low impedance source. The AD5541A operates
with a voltage reference ranging from 2 V to VDD. References
below 2 V result in reduced accuracy. The full-scale output
voltage of the DAC is determined by the reference. Table 8
outlines the analog output voltage or particular digital codes.
If the application does not require separate force and sense
lines, tie the lines close to the package to minimize voltage
drops between the package leads and the internal die.
POWER-ON RESET
The AD5541A has a power-on reset function to ensure that the
output is at a known state on power-up. On power-up, the DAC
register contains all 0s until the data is loaded from the serial
register. However, the serial register is not cleared on power-up;
therefore, its contents are undefined. When loading data initially
to the DAC, 16 bits or more should be loaded to prevent erroneous
data appearing on the output. If more than 16 bits are loaded,
the last 16 are kept, and if less than 16 bits are loaded, bits remain
from the previous word. If the AD5541A must be interfaced
with data shorter than 16 bits, pad the data with 0s at the LSBs.
POWER SUPPLY AND REFERENCE BYPASSING
For accurate high resolution performance, it is recommended
that the reference and supply pins be bypassed with a 10 μF
tantalum capacitor in parallel with a 0.1 μF ceramic capacitor.
