PIN DESCRIPTIONS
VDD
Power supply input.
GND
Power supply return.
VOUT1, VOUT2
The voltage output of the DACs. It is buffered by a unity-
gain follower that can slew up to 1V/µs.
VREFL1, VREFL2
The lower of the voltage reference inputs. VREFL must be
equal to or greater than ground and less than VREFH.
VREFH1, VREFH2
The higher of the voltage reference inputs. VREFH must be
equal to or less than VCC and greater than VREFL.
A0, A1, A2
The address inputs for the serial interface logic. Bias-
ing the address inputs will determine the device’s bus
address that is contained within the serial data stream
when communicating over the serial bus.
SCL
The serial interface clock. It is used to clock the data in and
out. When writing to the device data must remain stable
while SCL is high. When reading from the device data is
clocked out on the falling edge of SCL.
SDA
The bidirectional pin used to transfer data in and out of
the device.
CS
Chip Select input (VIH = selected) in the 9210. See the
Block Diagrams.
MUTE#
Mute input (VIL = mute) in the 9211. See the Block
Diagrams.
VREF
VREF output (1.25V) in the 9212. See the Block Diagrams.
Note: NC pins are not connected.
