DESCRIPTION
The X79000 is a family of Single Channel Non-Volatile
(NV) Digital-to-Analog Converters with integrated
voltage reference, configurable output buffer, general
purpose EEPROM, and selectable full scale and zero
offset voltages.
The X79000 series implements an SPI serial bus
interface with slave address identification allowing up
to 32 devices on some options. The full scale and
zero scale voltages and the DAC initial value register
can be set via the SPI bus interface. Optional pins
are provided for Up/Down style interface allowing for
increment and decrement of the DAC register in 1, 4,
or 16 steps at a time.
A Power-on Recall circuit is implemented to keep the
DAC output at high impedance on power-up and to load
an initial user defined value from non-volatile memory. A
power-up ready signal is provided to alert the system to
begin operations.
Additional general purpose non-volatile memory (56
Bytes) is provided for curve-fit profile setting, signal
conditioning parameters, or device and system
indentification.
