Part numberMAX329
CategoryAnalog & Mixed-Signal Processing => Analog Multipliers
DescriptionUltra-Low-Leakage, Single-Ended, Monolithic, CMOS Analog Multiplexer
The MAX328/MA329 are monolithic CMOS analog multiplexers. 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.

Ultra-Low Leakage Monolithic CMOS Analog Multiplexers

The MAX328/MA329 are monolithic CMOS analog multiplexers. The is a single-ended, 1-of-8 device, and the is a differential, 2-of-8 device. Designed to provide the lowest possible on- and offleakages, 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 40k resistor to each input makes the MAX328/MAX329 an excellent fault-tolerant multiplexer. Low leakage (less than at +25C) and 2.5k 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 40k). The MAX328/MAX329 work equally well with a single supply 30V or dual supplies to 18V. They also perform well with unbalanced combinations of supply voltage, such as +12V and or +5V and -15V. Low power dissipation (1.9mW with 15V supplies) allows use in portable applications.
