MAX4800A/MAX4802A
Low-Charge-Injection, 8-Channel, High-Voltage
Analog Switches with 20MHz Serial Interface

Detailed Description
The MAX4800A/MAX4802A provide high-voltage
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 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, or +40V/-160V. The digital interface oper-
ates 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 35k
Ω bleed resistors on each
switch terminal to discharge capacitive loads.
The devices are drop-in replacements for the Supertex
HV2203 and HV2303, respectively.
Analog Switch
The devices 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 devices allow a wide range of high-voltage sup-
plies.
The
devices
operate
with
VNN from
-160V to -15V and VPP from +40V to (VNN + 200V).
When VNN is connected to GND (single-supply applica-
tions), the devices operate with VPP up to +200V.
