Factory Settings For Step 1. FIGURE 8. Factory Settings for Step 3. Step 2 — On-Board Input Amplifier Step 4 — Convert Command Generator 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 duration, 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) soldered to the board.
