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. The ±2.5 V supplies should also be bypassed to ground at the converter.
4. VLR and the power supply ground for the ±2.5 V should be
connected to the same ground plane under the chip.
5. SCLK and SDO may require pull-down resistors in some applications.
