Figure 98. Output Amplifier and Offset DAC
OUTPUT AMPLIFIERS
The output amplifiers can swing to 0.5V below the positive supply and 0.5V above the negative supply. This
condition limits how much the output can be offset for a given reference voltage. The maximum range of the
output for ±17V power and a +5.5V reference is â16.5V to +16.5V for gain = 6.
Each output amplifier is implemented with individual over-current protection. The amplifier is clamped at 8mA,
even if the output current goes over 8mA.
