Detailed Description
The MAX4800/MAX4801/MAX4802 provide high-volt-
age switching on eight channels for ultrasound 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, or +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 35k
Ω 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, respectively.
The MAX4801 is a drop-in replacement for the Supertex
HV20320.
Analog Switch
The MAX4800/MAX4801/MAX4802 allow a peak-to-
peak analog signal range from VNN + 10V to VPP - 10V.
Analog switch inputs must be unconnected, or satisfy
VNN
≤ (VCOM_, VNO_) ≤ VPP during power-up and
power-down.
High-Voltage Supplies
The MAX4800/MAX4801/MAX4802 allow a wide range
of high-voltage supplies. The devices operate with VNN
from -160V to -15V and VPP from +40V to VNN + 200V.
