National Semiconductor Application Note 1626 Mike Stout July 2007 Hardware Setup REGISTER PROGRAMMING SETUP 1. To use the on-board logic circuit to program the LMP8100 Register connect the jumpers as follows: JP1 – Pins 2 and 3 JP2 – Pins 2 and 3 JP3 – Pins 2 and 3 2. To use an external microcontroller to program the LMP8100 Register connect the jumpers as follows: JP1 – Pins 1 and 2 JP2 – Pins 1 and 2 JP3 – Pins 1 and 2 Connect the external microcontroller to J3. POWER SUPPLY SETUP 1. +5V Supply Connect the jumper as follows: JP4 – GND and the center pin Connect a +5V supply to the V+ and GND banana plugs. 2. ±2.5V Supply Connect the jumper as follows: JP4 – V− and the center pin Connect a +2.5V supply to the V+ banana plug, a −2.5V supply to the V− banana plug, and supply grounds to the GND banana plug. GRT PIN SETUP 1. To connect the GRT pin to ground Connect the jumpers as follows: JP5 – GND and the center pin JP6 – GND and the center pin 2. To connect the GRT pin to a Low-Impedance Source Connect the jumpers as follows: JP5 – DC and the center pin JP6 – V+ and the center pin 3. To connect the GRT pin to an AC ground Connect the jumpers as follows: JP5 – AC GND and the center pin JP6 – GND and the center pin COMPONENTS Various loads can be insta...
