ADDITIONAL COMMENTS
The demonstration board includes test points for convenience on the bench. The +5V
and GND test points connect to the board’s supply voltages. The CH0 test point
connects to the PGA’s CH0 input; it is also connected to the voltage divider’s output
(with filtering). The CH1 test point allows the user to place any desired signal at the
PGA’s CH1 input.
The PIC16F684 (and 10-bit ADC) are not part of the demo board schematic; see
Figure 1-3 instead.
The PICkit 1 Flash Starter Kit provides a +5V single supply voltage. It can drive up to
5 µF on the supply; a larger capacitive load causes current loading and timing issues.
The PICkit 1 Flash Starter Kit Signal Analysis PICtail Daughter Board uses the +5V
single supply voltage. It has 0.1 µF local bypass capacitors for each IC, and a 1 µF bulk
bypass capacitor for the entire board.
This demonstration board also uses the +5V single supply voltage. It has a 0.1 µF local
bypass capacitor for the PGA, and a 1 µF bulk bypass capacitor for the entire board. A
solid ground plane provides a good ground for the PGA.
High-frequency design practices are used to minimize digital interference:
• Solid ground plane
• Surface-mount devices
• Separate digital and analog lines and sections
• Straight and short lines to the PGA
