1 The AD394 T grade is available to MIL-STD-883, Method 5008, Class B. See Analog Devices Military Catalog (1985) for proper part number and detail specification.

2 Timing specifications appear in Table 5 and Figure 6.

3 See the Theory of Operation section for code tables and graphs.

4 FSR means full-scale range and is equal to 20 V for a ±10 V bipolar range and 10 V for a 0 V to 10 V unipolar range.

5 Integral nonlinearity is a measure of the maximum deviation from a straight line passing through the endpoints of the DAC transfer function.

6 This is a measure of the amount of charge injected from the digital inputs to the analog outputs when the inputs change state. It is usually specified as the area of the

glitch in nVs and is measured with VREFIN = AGND.

7 Digital crosstalk is defined as the change in any one output’s steady state value as a result of any other output being driven from VOUTMIN to VOUTMAX into a 2kΩ load by

means of varying the digital input code.

8 Reference crosstalk is defined as the change in any one output as a result of any other output being driven from VOUTMIN to VOUTMAX @10 kHz into a 2 kΩ load by means

of varying the amplitude of the reference signal.

9 The AD394 can be used with supply voltages as low as ±11.4 V. See Figure 10.
