"T" Model LSN-T/16-D12
This version of the LSN 16A series offers a special output voltage trimming
feature which is fully compatible with competitive units. The output voltage
may be varied from 0.75 to 5 Volts using a single external trim up resistor con-
nected from the Trim input to Output Common. If no trim resistor is attached
(Trim pin open), the output is 0.7525 Volts.

low temperature coeffi cient (±100 ppm/°C or less) mounted close to the con-
verter with short leads. Also be aware that the output accuracy is ±2% (typical)
therefore you may need to vary this resistance slightly to achieve your desired
output setting.
The resistor trim up equation for the LSN-T/16-D12 is as follows:

Voltage Trim
The LSN-T/16-D12 may also be trimmed using an external voltage applied
between the Trim Input and Output Common. Be aware that the internal “load”
impedance looking into trim pin is approximately 5kΩ. Therefore, you may
have to compensate for this in the source resistance of your external voltage
reference.
The equation for this voltage adjustment is:
