General Information
Jumper JP4:
1–2 — Connects the input of the B-channel PGA (U1: D) to the signal
from JP3
2–3 — Connects the input of the B-channel PGA (U1: D) to the output
of the B-channel preamplifier (U1:C)
Jumper JP5:
1–2 — Connects the THS7002 IC positive clamp input pin (VH) to Vcc
when switch S2:F is set appropriately
2–3 — Connects the THS7002 IC positive clamp input pin (VH) to +5V
when switch S2:F is set appropriately
For example, to use a single-ended input and use the preamplifiers as buffers
and gain:
1) Set JP1 to 2–3
2) Set JP2 to 2–3
3) Set JP3 to 1–2
4) Set JP4 to 2–3
5) Apply the input to input A (J6)
The output of the THS7002 PGAs is a differential signal due to the inverter
(U2). For either an independent or differential signal source, JP3 should be set
to the 2–3 position.
