Low-Charge Injection,

8-Channel, High-Voltage Analog Switches

General Description

The MAX4800/MAX4801/MAX4802 provide high-volt-

age switching on eight channels for ultrasonic imaging

and printer applications. The devices utilize BCDMOS

process technology to provide eight high-voltage low-

charge-injection SPST switches, controlled by a digital

interface. Data is clocked into an internal 8-bit shift reg-

ister and retained by a programmable latch with enable

and clear inputs. A power-on reset function ensures

that all switches are open on power-up.

The MAX4800/MAX4801/MAX4802 operate with a wide

range of high-voltage supplies including: VPP/VNN =

+100V/-100V, +185V/-15V, and +40V/-160V. The digital

interface operates from a separate VDD supply from

+2.7V to +13.2V. Digital inputs DIN, CLK, LE, and CLR

are +13.2V tolerant, independent of the VDD supply

voltage. The MAX4802 provides integrated 35kΩ bleed

resistors on each switch terminal to discharge capaci-

tive loads.

The MAX4800 and MAX4802 are drop-in replacements

for the Supertex HV20220 and HV232. The devices are

available in the 48-pin TQFP, 26-bump CSBGA, 28-pin

PLCC, and 48-pin TQFN packages. The MAX4801 is a

drop-in replacement for the Supertex HV20320 and is

available in the 28-pin PLCC package. All devices are

specified for the commercial 0°C to +70°C temperature

range.
