Ultra5000 Connector Information

Analog Outputs

There are two analog outputs to use as needed. A 12 bit D/A
converter generates an analog representation of the digital command
value. The analog outputs are set to zero after the power comes up.

Figure 2.12

shows the configuration of the analog outputs.

Analog Output Configuration

The following table provides a description of the analog output
specifications.

Offset Error

Deviation from the correct value expected from
analog-to-digital conversion when 0V is applied
to the input.

50 mV

Gain Error

Deviation of the transfer function from unity
gain, expressed in a percent of full scale.

1%

Propagation
Delay

Delay from the input to the firmware-accessible
registers.

100 mS

IMPORTANT

Output values can vary during power-up until the
specified power supply voltage is reached.
