MAX4800CQI

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4800CQI is an eight-channel single-pole single-throw (SPST) normally open analog switch integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 13.2V. The device features a maximum on-resistance of 38 ohms with a channel-to-channel matching of 1.9 ohms. Switching times for both turn-on and turn-off are limited to 5 microseconds. Key electrical parameters include a charge injection of 820 picocoulombs, off-state leakage current of 4 microamperes maximum, and a crosstalk specification of -80dB at 5MHz. The component is housed in a 28-PLCC package with dimensions of 11.51x11.51mm and supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Eight independent SPST signal paths provide flexible routing capabilities within a compact integrated circuit.
