INTRODUCTION
The SMP9210, -11, -12 trio are serial input, voltage
output, dual 10-Bit digital to analog converters. They can
operate from a single 2.7V to 5.5V supply. Internal
precision buffers swing rail-to-rail with an input reference
range from ground to the positive supply.
They integrate two 10-Bit DACs and their associated
circuits: an enhanced unity gain operational amplifier
output, a 10-Bit volatile data latch, a 10-bit nonvolatile
data register and an industry standard 2-wire serial
interface.
Programming of configuration, control and calibration
values by the user can be simplified with the interface
adapter and Windows GUI software obtainable from
Summit Microelectronics.
RECOMMENDED OPERATING CONDITIONS
Temperature –40ºC to 85ºC.
Voltage 2.7V to 5.5V

A0, A1, A2
The address inputs for the serial interface logic. Biasing the address inputs will determine the device’s bus
address that is contained within the serial data stream
when communicating over the serial bus.
PIN DESCRIPTIONS
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.
