MAX4800A/MAX4802A
Low-Charge-Injection, 8-Channel, High-Voltage
Analog Switches with 20MHz Serial Interface
General Description
The MAX4800A/MAX4802A provide high-voltage switch-
ing on eight channels for ultrasonic imaging and printer
applications. The devices utilize BCDMOS process tech-
nology to provide eight high-voltage low-charge-injection
SPST switches, controlled by a 20MHz serial interface.
Data is clocked into an internal 8-bit shift register 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 devices 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 +6V. Digital inputs
DIN, CLK, LE, and CLR are +6V tolerant, independent
of the VDD supply voltage. The MAX4802A provides
integrated 35kΩ bleed resistors on each switch terminal
to discharge capacitive loads.
The devices are drop-in replacements for the Supertex
HV2203 and HV2303. They are available in the 48-pin
LQFP, 26-bump CSBGA, and 28-pin PLCC packages. All
devices are specified for the commercial 0°C to +70°C
temperature range.
