HV2701

Low Charge Injection 16-Channel

High Voltage Analog Switch with Bleed Resistors

Features

General Description

► HVCMOS technology for high performance

► Integrated bleed resistors on the outputs

► 16 Channels of high voltage analog switch

► 3.3V input logic level compatible

► 20MHz data shift clock frequency

► Very low quiescent power dissipation-10µA

► Low parasitic capacitance

The Supertex HV2701 is a low charge injection, 16-channel,

high voltage, analog switch integrated circuit (IC) with bleed

resistors. The device can be used in applications requiring

high voltage switching controlled by low voltage control

signals, such as medical ultrasound imaging and piezoelectric

transducer drivers. The bleed resistors eliminate voltage built

up on capacitive loads such as piezoelectric transducers.

► DC to 10MHz analog signal frequency

► -60dB typical off-isolation at 5MHz

► CMOS logic circuitry for low power

► Excellent noise immunity

Input data is shifted into a 16-bit shift register that can then

be retained in a 16-bit latch. To reduce any possible clock

feed-through noise, the latch enable bar should be left high

until all bits are clocked in. Data is clocked in during the rising

edge of the clock. Using HVCMOS technology, this device

combines high voltage bilateral DMOS switches and low

power CMOS logic to provide efﬁcient control of high voltage

analog signals.

► Cascadable serial data register with latches

► Flexible operating supply voltages

Applications

► Medical ultrasound imaging

► NDT metal ﬂaw detection

► Piezoelectric transducer drivers

► Optical MEMS modules

The device is suitable for various combinations of high

voltage supplies, e.g., V_PP/V_NN: +40V/-160V, +100V/-100V,

and +160V/-40V.
