AD5305/AD5315/AD5325
FUNCTIONAL DESCRIPTION
The AD5305/AD5315/AD5325 are quad resistor-string DACs
fabricated on a CMOS process with resolutions of 8, 10, and 12
bits, respectively. Each contains four output buffer amplifiers
and is written to via a 2-wire serial interface. They operate from
single supplies of 2.5 V to 5.5 V, and the output buffer amplifiers
provide rail-to-rail output swing with a slew rate of 0.7 V/
μ
s.
The four DACs share a single reference input pin. The devices
have three programmable power-down modes, in which all
DACs may be turned off completely with a high impedance
output, or the outputs may be pulled low by on-chip resistors.
Digital-to-Analog Section
The architecture of one DAC channel consists of a resistor-string
DAC followed by an output buffer amplifier. The voltage at the
REFIN pin provides the reference voltage for the DAC. Figure 4
shows a block diagram of the DAC architecture. Since the input
coding to the DAC is straight binary, the ideal output voltage is
