MAX388CPN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX388CPN+ is a high-voltage analog multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features an 8:1 single-circuit configuration housed in an 18-PDIP package. The device operates on dual supply voltages ranging from ±4.5 V to ±18 V, with a typical operating voltage of 15 V. Key electrical parameters include a maximum on-resistance of 3 kOhms and a channel-to-channel matching of 300 Ohms. Switching performance is defined by a maximum turn-on time of 1.5 µs and a turn-off time of 1 µs. Additional specifications include a charge injection of 55 pC, off-state leakage current of 500 pA, and a power dissipation of 889 mW.
