9 Power Supply Recommendations

The ONET2804TLP is designed to operate from an input supply voltage range between 2.8 V and 3.47 V. There are a total of eight power-supply pads (VCCI[4:1] and VCCO[4:0]) that must be connected for proper operation. VCCI[4:1] are used to supply power to the input transimpedance amplifier stages and VCCO[4:1] are used to supply power to the voltage amplifiers and output buffers. Each amplifier is powered up separately but there are some common internal connections for support circuitry (such as the two-wire interface). Therefore, if only one channel is being evaluated, all eight supply pads must be connected. Use two single-layer ceramic (SLC) capacitors in the range of 270 pF to 680 pF for power-supply decoupling. VCCI1, VCCI2, VCCO1, and VCCO2 should be bonded to one capacitor and VCCI3, VCCI4, VCCO3, and VCCO4 should be bonded to the other capacitor; see Figure 24 and Figure 27 for reference.
