8-channel high voltage analog switch chip MAX4800ACCM -- 8 x SPST 25 Ohms LQFP-48

Overview

‌MAX4800ACCM is an 8-channel high voltage analog switch chip for ultrasonic imaging and printer applications. ‌MAX4800ACCM uses BCDMOS technology to provide eight high voltage low charge injection single pin single throw (SPST) switches, controlled through a 20MHz serial interface. The data is moved into the internal 8-bit shift register and held by a programmable latch with enable and clear inputs. The power-on and reset function ensures that all switches are enabled during power-on ‌.

Main characteristics

Control interface ‌ : MAX4800ACCM adopts 20MHz serial interface for control.

Number of switches ‌ : MAX4800ACCM offers eight high-voltage low-charge injection single-pole single-throw (SPST) switches.

Data store ‌ : Data is moved into an internal 8-bit shift register and held via a programmable latch.

Power management ‌ : MAX4800ACCM supports a wide range of high voltage power supplies, including VPP/VNN = +100V/-100V, +185V/-15V, and +40V/-160V. The digital interface operates on a separate +2.7V to +6V power supply.

Input tolerance ‌ : Digital inputs DIN, CLK, /LE, and CLR have a +6V tolerance independent of the VDD supply voltage.

Alternative ‌ : MAX4800ACCM is a direct replacement for the Supertex HV20220.
