Operation with Supply Voltages
Other Than ±15V
Maxim guarantees the DG528/DG529 for operation
from ±4.5V to ±20V supplies. The switching delays
increase by about a factor of two at ±5V, and break-
before-make action is preserved.
The DG528/DG529 can operate with a single +5V to
+30V supply as well as asymmetrical power supplies
like +15V and -5V. The digital threshold will remain
approximately 1.6V above the GND pin, and the analog
characteristics such as rDS(ON) are determined by the
total voltage difference between V+ and V-. Connect V-
to 0V when operating with a +5V to +30V single supply.
Digital Interface Levels
The typical digital threshold of both the address lines
and EN is 1.6V with a temperature coefficient of
approximately -3mV/°C, ensuring compatibility with TTL
logic over the temperature range. The digital threshold
is relatively independent of the power-supply voltages,
going from a typical 1.6V when V+ is 15V to 1.5V typi-
cal with V+ = 5V. Therefore, Maxim’s DG528/DG529
operate with standard TTL logic levels, even with ±5V
power supplies. In all cases, EN’s threshold is the same
as the other logic inputs and is referenced to GND.
The digital inputs can also be driven with CMOS logic
levels swinging from either V+ to V- or from V+ to GND.
The digital input current is just a few nanoamps of leak-
age at all input-voltage levels with a guaranteed maxi-
mum of 1A. The digital inputs are protected from ESD
by a 30V zener diode between the input and V+ and
can be driven ±2V beyond the supplies without draw-
ing excessive current.
