Notes:

1.

Digital input voltage must not exceed supply voltage or go below –0.5V ; “0” <0.8V; 2.4V < “1”

≤V

DD.

2.

AC or DC; use R6758–1 for fixed reference applications

3.

Using the internal feedback resistor and an external op amp. The Scale Factor can be adjusted externally by variable resistors in series with the

reference input and/or in series to the internal feedback resistor. Please refer to the Applications Information section.

4.

At 25

°C; the output leakage current will create an offset voltage at the external op amps output. It doubles every 10°C temperature increase.

5.

Integral Linearity is measured as the arithmetic mean value of the magnitudes of the greatest positive deviation and the greatest negative deviation from

the theoretical value for any given input combination.

6.

Differential Linearity is the deviation of an output step form the theoretical value of 1LSB for any two adjacent digital input codes.

7.

At 25

°C, the output leakage current will create an offset voltage output. It doubles every 10°C temperature increase.

8.

Using the internal feedback resistor and an external op amp.

9.

Use series 470ohm resistor to limit start-up current.
