HS-2420RH
Offset and Gain Adjustment
Offset Adjustment
The offset voltage of the HS-2420RH may be adjusted using
a 100k
trim pot, as shown in Figure 15. The recommended
adjustment procedure is:
1. Apply 0V to the sample-and-hold input, and a square
wave to the S/H control.
2. Adjust the trim pot for 0V output in the hold mode.
Gain Adjustment
The linear variation in pedestal voltage with sample-and-
hold input voltage causes a -0.06% gain error
(CH = 1000pF). In some applications (D/A deglitcher, A/D
converter) the gain error can be adjusted elsewhere in the
system, while in other applications it must be adjusted at the
sample-and-hold. The two circuits shown below demonstrate
how to adjust gain error at the sample-and-hold.
The recommended procedure for adjusting gain error is:
1. Perform offset adjustment.
2. Apply the nominal input voltage that should produce a
+10V output.
3. Adjust the trim pot for +10V output in the hold mode.
4. Apply the nominal input voltage that should produce a -10V
output.
5. Measure the output hold voltage (V-10 NOMINAL). Adjust
the trim pot for an output hold voltage of:
V-10 NOMINAL
