NOTES

1. See Section 3.3 Voltage Reference for information on

required voltage reference performance criteria.

2. Locate capacitors so as to minimize loop length.

3. V1-, V2-, and VLR should be connected to the same

ground plane under the chip.

4. SCLK and SDO may require pull-down resistors in

some applications.
