Gain Adjust
STEP-BY-STEP
BASIC OPERATIONS
B) To adjust gain, install RV2 (50kΩ) and R2 (576kΩ), then
adjust RV2. Do this for +10V and –10V. See Figure 8.
STEP 1 — ADS7804P OR ADS7805P
NOTE: The offset directly affects the gain. Always trim
offset first. For maximum precision, more than one iteration
of these adjustments may be required.
A) To test the ADS7804P, install an ADS7804P in U1.
B) To test the ADS7805P, install an ADS7805P in U1.
Factory Setting: ±10V input range without offset/gain trim,
R1 and R4 soldered to the board.
Factory Setting: C3, C4, C5, C6 and 28-pin socket (U1)
soldered to the board. ADS7805P plugged into U1.

Step 4 — Convert Command Generator
Step 2 — On-Board Input Amplifier
To use the on-board input amplifier, jumpers J1 and J2 must
be set to the “B” position, and P1 (Optional Power) must be
supplied with ±15V. The factory setting of the amplifier
yields an inverting gain of 2. Combinations of resistors R6,
R7, and R8 will affect the gain of the amplifier as follows:
A) J3 set to “INT” selects the on-board convert command
generator operating at 100kHz (divided down from 1MHz
by U3).
B) J3 set to “EXT” selects an external convert command
generator. Apply a negative-going pulse, 100ns in dura-
tion, to P4 (External Convert Command). This connector
is terminated on the board with a 50Ω resistor (R9).
Adjust the voltage of the generator for a 0V to 5V swing
and the pulse rate to the desired frequency (≤100kHz).
NOTE: When using an external convert command, the
trace powering the on-board convert command generator
can be cut to eliminate any noise contributions due to the
oscillator. To reconnect, install a jumper at J4.
GAIN = – (R8)/(R6 || R7)
NOTE: The on-board input amplifier may improve the
quality of the signal reaching the ADS7804P or ADS7805P.
This depends on the output characteristics of the signal
generator.
Factory Setting: J1 and J2 set to “A”, bypassing the
amplifier, R6, R7, R8, C1, C2 and 8-pin socket (U2) sol-
dered to the board. OPA671 plugged into U2.
Factory Setting: J3 set to “INT”, conversions synchronized
to on-board convert command generator at 100kHz. P4, R9,
U3, U7, C7 and C11 soldered to the board.
