DG528CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG528CJ is an 8-channel analog multiplexer switch manufactured by Analog Devices Inc./Maxim Integrated. It features a single 8:1 circuit configuration housed in an 18-pin PDIP package with a width of 0.300 inches (7.62 mm). The device supports single supply voltages ranging from 5V to 30V and dual supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 450 ohms, channel-to-channel matching of 27 ohms, and a charge injection of 4pC. Switching times are specified at 1.5µs for both turn-on and turn-off. Leakage current is limited to 5nA maximum, with off-channel capacitance values of 5pF and 25pF.
