Bipolar Supplies
The MAX349/MAX350 operate with bipolar supplies
from ±3.0V and ±8V. The V+ and V- supplies need not
be symmetrical, but their sum cannot exceed the
absolute maximum rating of 17V. Do not connect the
MAX349/MAX350 V+ to +3V and connect the logic-
level pins to TTL logic-level signals. This exceeds
the absolute maximum ratings and can damage the
part and/or external circuits.
Single Supply
The MAX349/MAX350 operate from single supplies
between +3V and +16V when V- is connected to GND.
All of the bipolar precautions must be observed.
High-Frequency Performance
In 50
systems, signal response is reasonably flat up
to 50MHz (see
Typical Operating Characteristics).
Above 20MHz, the on response has several minor
peaks that are highly layout dependent. The problem is
not turning the switch on, but turning it off. The off-state
switch acts like a capacitor and passes higher frequen-
cies with less attenuation. At 10MHz, off-isolation is
about -45dB in 50
systems, becoming worse (approx-
imately 20dB per decade) as frequency increases.
Higher circuit impedances also make off-isolation
worse. Adjacent channel attenuation is about 3dB
above that of a bare IC socket, and is entirely due to
capacitive coupling.
