DESCRIPTION

NV DAC with Selectable Output Range

and Memory

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.

FEATURES

• 12-Bit Resolution

• Selectable full scale and zero scale voltages

• Optional External full scale and zero scale

references

• Programmable, non-volatile DAC initial value

• Optional UP/DOWN interface

• Guaranteed Monotonic Operation, <0.5LSB DNL

• Buffered Output Option

• Integrated Voltage Reference Option

• Voltage Reference Output (1.21V) Option

• 6 µs settling time, full scale

• SPI interface, 5MHz

• Up to 5 slave Address Pins

• Power-up recall and ready output

• 56 Bytes of general purpose EEPROM

• Asynchronous clear pin and control bit

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.

• V = 5V ±10%

• 20-lead TSSOP

• NV DAC
