Pulling the MODE pin low places the XTR200 into voltage-output mode. Figure 6-4 shows the internal configuration of the device in voltage-output mode. Amplifier A2 is now bypassed and the inverted output of amplifier A1 controls the output transistor Q2 through switch SW4. Switches SW2 and SW3 close the feedback loop through the on-chip voltage divider consisting of 110kΩ and 40kΩ resistors. These resistors are fabricated using a high-precision thin-film deposition and precision layout techniques to deliver extremely low gain error over the full temperature range.
The on-chip, precision voltage divider determines the transfer function in voltage output mode:
In voltage-output mode, the gate of transistor Q1 is connected to ground and no current flows from the SET pin. A resistor present at the SET pin, RSET, does not affect voltage output operation. This allows the XTR200 to operate in voltage or current output mode without changing external components.
