For proper operation, power supply decoupling is required. It
should be done using a 0.1
μ
F ceramic capacitor in parallel
with a 0.01
μ
F chip capacitor for each group of V
AA
pins to
ground. These capacitors should be located as close to the
V
AA
and GND pins as possible, using short, wide traces.
If a separate linear regulator is used to provide power to the
HMP8154/HMP8156A power plane, the power-up sequence
should be designed to ensure latchup will not occur. A separate
linear regulator is recommended if the power supply noise on
the V
AA
pins exceeds 200mV. About 10% of the noise (that is
less than 1MHz) on the V
AA
pins will couple onto the analog
outputs.
External Reference Voltage
If an external reference voltage is used, its circuitry should
receive power from the same plane as the HMP8154/
HMP8156A. The external VREF must also be stable and well
decoupled from the power plane. An example VREF circuit
using a band gap reference diode is shown in Figure 37.
