CALIBRATION PROCEDURE
1. Connect the converter per Figure 3, Figure 4, and Table 1
for the appropriate input range. Apply a pulse of 150
nanoseconds to the START CONVERT input (pin 16) at a
rate of 250kHz. This rate is chosen to reduce flicker if
LED’s are used on the outputs for calibration purposes.
2.
Zero Adjustments
Apply a precision voltage reference source between the
amplifier’s analog input and ground. Adjust the output of the
reference source per Table 2. For unipolar, adjust the zero
trimming potentiometer so that the output code flickers
equally between 0000 0000 0000 and 0000 0000 0001 with
the pin 18 tied high (straight binary) or between 1111 1111
1111 and 1111 1111 1110 with the pin 18 tied low (comple-
mentary binary).
For bipolar operation, adjust the potentiometer such that
the code flickers equally between 1000 0000 0000 and
1000 0000 0001 with pin 18 tied high (offset binary) or
between 0111 1111 1111 and 0111 1111 1110 with pin 18
tied low (complementary offset binary).
3.
Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 1. Adjust the gain trimming potentiom-
eter so that the output code flickers equally between 1111
1111 1110 and 1111 1111 1111 for pin 18 tied high or
between 0000 0000 0001 and 0000 0000 0000 for pin 18
tied low.
4. To confirm proper operation of the device, vary the preci-
sion reference voltage source to obtain the output coding
listed in Table 3.
