INTRODUCTION
The SMP9410 is a quad 10 bit (1024 steps) Non Volatile
D-to- A converter or DACPOTTM. The device will recall any
analog voltage on power up, making it ideal for high
accuracy and temperature stable calibration purposes and
can operate from a single +2.7V to +5.5V supply. Internal
precision buffers swing rail-to-rail with an input voltage
range from ground to the positive supply.
The part integrates four 10-bit DACs and associated cir-
cuits: an enhanced unity gain operational amplifier output,
a 10-bit volatile data latch, a 10-bit nonvolatile data register,
and I2C bus industry standard 2-wire serial interface. The
SMP9410 is available in a very small 5mm square Quad Flat
package with No leads (QFN) for small form factor designs.
Programming of configuration, control and calibration val-
ues by the user can be simplified with the interface adapter
and Windows GUI software obtainable from Summit Micro-
electronics.

Preliminary Information
DEVICE OPERATION
INTRODUCTION
The device has four 10-Bit digital to analog converters that
are comprised of a resistor network that converts a digital
input into an equivalent analog output voltage in proportion
to the applied reference voltages. The voltage differential
between each VREFL and VREFH input pair sets the range
and full-scale output voltage for their respective DAC.
Each DAC has a 10-Bit nonvolatile register that can hold a
www.DataSheets4eUt.-caonmd-forget’ value that can be recalled whenever the
device is powered-on.
Each DAC has a 10-Bit volatile register that holds the
current digital value. The register can be set to any value
by the serial interface; commanded to load the zero scale
value, full scale value or mid-scale value; or can recall a
preset value stored in a nonvolatile register.
The device also has a nonvolatile configuration register that
is accessible over the 2-wire bus. The configuration register
is used to select the device type identifier and the DAC
power-on state.
The device uses the industry standard I2C 2-wire serial
protocol. The bus is designed for two-way, two-line serial
communication between different integrated circuits. The
two lines are the SCL (serial clock) and SDA (serial data).
Both lines should be pulled up to the positive supply through
a resistor. The protocol defines devices as being either
Masters or Slaves. The SMP9410 will always be a Slave
because it does not initiate any communications or provide
a clock output.
