FUNCTIONAL DESCRIPTION
The AD5330/AD5331/AD5340/AD5341 are single resistor-string
DACs fabricated on a CMOS process with resolutions of 8, 10,
12, and 12 bits, respectively. They are written to using a parallel
interface. They operate from single supplies of 2.5 V to 5.5 V and
the output buffer amplifiers offer rail-to-rail output swing. The
AD5330, AD5340, and AD5341 have a reference input that may
be buffered to draw virtually no current from the reference
source. The reference input of the AD5331 is unbuffered. The
devices have a power-down feature that reduces current con-
sumption to only 80 nA @ 3 V.
Digital-to-Analog Section
The architecture of one DAC channel consists of a reference
buffer and a resistor-string DAC followed by an output buffer
amplifier. The voltage at the V
REF
pin provides the reference
voltage for the DAC. Figure 27 shows a block diagram of the
DAC architecture. Since the input coding to the DAC is straight
binary, the ideal output voltage is given by:
