Low-Charge Injection, 8-Channel, High-Voltage Analog Switches
General DescriptionThe 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 VDDsupply from
+2.7V to +13.2V. Digital inputs DIN, CLK, LE, and CLR
are +13.2V tolerant, independent of the VDDsupply
voltage. The MAX4802 provides integrated 35kΩbleed
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, and 28-
pin PLCC 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.
