MAX329EWE+T

P1-P3P4-P6P7-P9P10-P10
General Description
The MAX328/MA329 are monolithic CMOS analog multi-
plexers. The MAX328 is a single-ended, 1-of-8 device,
and the MAX329 is a differential, 2-of-8 device.
Designed to provide the lowest possible on- and off-
leakages, these multiplexers switch signals from high
source impedance, providing the mux operates into a
high-input-impedance op amp or A/D converter. The
MAX328/MAX329 are pin-for-pin replacements for the
popular DG508/DG509 in these applications.
Adding an external 40kΩ resistor to each input makes
the MAX328/MAX329 an excellent fault-tolerant multi-
plexer. Low leakage (less than 1pA at +25°C) and
2.5kΩ on-resistance allow the circuit to sustain 110V
AC faults indefinitely while maintaining an error of less
than 40nV for normal signals (i.e., 1pA times 40kΩ).
The MAX328/MAX329 work equally well with a single
supply of 10V to 30V or dual supplies of ±5V to ±18V.
They also perform well with unbalanced combinations of
supply voltage, such as +12V and -5V or +5V and -15V.
Low power dissipation (1.9mW with ±15V supplies)
allows use in portable applications.
