HV232

Low Charge Injection 8-Channel High Voltage

Analog Switches with Bleed Resistors

Features

General Description

► HVCMOS^®technology for high performance

► Very low quiescent power dissipation (10µA max.)

► Output on-resistance (22Ω typ.)

The Supertex HV232 is a low charge injection 8-channel,

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

resistors. This device can be used in applications requiring

high voltage switching controlled by low voltage control

signals, such as ultrasound imaging and printers. The bleed

resistors eliminate voltage built up on capacitive loads such

as piezoelectric transducers. Input data is shifted into an 8-bit

shift register which can then be retained in an 8-bit latch. To

reduce any possible clock feed-through noise, Latch Enable

(LE) should be left high until all bits are clocked in. Using

HVCMOS^®technology, this switch combines high voltage

bilateral DMOS switches and low power CMOS logic to

provide efﬁcient control of high voltage analog signals.

► Integrated bleed resistors on the outputs

► Low parasitic capacitances

► DC to 50MHz small signal frequency response

► -60dB typical output off isolation at 5.0MHz

► CMOS logic circuitry for low power

► Excellent noise immunity

► On-chip shift register, latch and clear logic circuitry

► Flexible high voltage supplies

Applications

► Medical ultrasound imaging

This IC is suitable for various combinations of high voltage

supplies, e.g., V_PP/V_NN: +50V/–150V, or +100V/–100V.

► Piezoelectric transducer drivers
