HV2802/HV2902

Low Harmonic Distortion, 32-Channel SPST,

High-Voltage Analog Switch

Features

General Description

• 32-Channel SPST (Single-Pole, Single-Throw)

High-Voltage Analog Switch

The HV2802 and HV2902 are low-charge injection,

32-channel, high-voltage analog switches intended for

use in applications requiring high-voltage switching

controlled by low-voltage control signals, such as

medical ultrasound imaging, driving piezoelectric

transducers and printers. The HV2902 has integrated

bleed resistors which eliminate voltage build-up on

capacitive loads such as piezoelectric transducers.

• 3.3V or 5.0V CMOS Input Logic Level

• 20 MHz Data Shift Clock Frequency

• High-Voltage CMOS (HVCMOS) Technology for

High Performance

• Very Low Quiescent Power Dissipation (10 µA)

• Low Parasitic Capacitance

Input data are shifted into a 32-bit shift register that can

then be retained in a 32-bit latch. To reduce any

possible clock feedthrough noise, the latch enable bar

should be left high until all bits are clocked in. Data are

clocked in during the rising edge of the clock. Using the

HVCMOS technology, this device combines

high-voltage bilateral DMOS switches and low-power

CMOS logic to provide efficient control of high-voltage

analog signals.

• DC to 50 MHz Analog Signal Frequency

• -60 dB Typical OFF-Isolation at 5.0 MHz

• CMOS Logic Circuitry for Low Power

• Excellent Noise Immunity

• Cascadable Serial Data Register with Latches

• Flexible Operating Supply Voltages

• Integrated Bleed Resistors on the Outputs

(HV2902 only)

The device is suitable for various combinations of

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

+100V/-100V and +160V/-40V.
