ADA4922-1
PRINTED CIRCUIT BOARD LAYOUT
CONSIDERATIONS
Although the ADA4922-1 is used in many applications
involving frequencies that are well below 1 MHz, some general
high speed layout practices must be adhered to because it is a
high speed amplifier. Controlled impedance transmission lines
are not required for low frequency signals, provided the signal
rise times are longer than approximately 5 times the electrical
delay of the interconnections. For reference, typical 50 Ω
transmission lines on FR-4 material exhibit approximately
140 ps/in delay on outer layers and 180 ps/in for inner layers.
Most connections between the ADA4922-1 and the
ADC can be kept very short.
Broadband power supply decoupling networks should be placed
as close as possible to the supply pins. Small surface-mount
ceramic capacitors are recommended for these networks, and
tantalum capacitors are recommended for bulk supply
decoupling.
