HV2801/HV2901

32-Channel Low-Charge-Injection High-Voltage Analog Switches

Features

General Description

• 32-Channel High-Voltage Analog Switch

The HV2801 and HV2901 are 32-channel

low-charge-injection high-voltage analog switch

integrated circuits (ICs) intended for applications

requiring high-voltage switching controlled by

low-voltage control signals, such as medical ultrasound

imaging, piezoelectric transducer drivers and printers.

The HV2901 has integrated bleed resistors to eliminate

voltage built up on capacitive loads such as

piezoelectric transducers.

• Integrated Bleed Resistors on the Outputs for

HV2901

• CMOS Logic Circuitry for Low Power

• 3.3V or 5V CMOS Input Logic Level

• 2:1 Multiplexer/Demultiplexer

• 20 MHz Data Shift Clock Frequency

• 10 µA Low-Quiescent Power Dissipation

• Low Parasitic Capacitance

Input data is shifted into a 32-bit Shift register that can

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

possible clock feed-through noise, the latch enable

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

are clocked in during the rising edge of the clock.

These devices combine 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 MHz

• Excellent Noise Immunity

• Cascadable Serial Data Register with Latches

• Flexible Operating Supply Voltages

Applications

The HV2801 and HV2901 are suitable for various

combinations of high-voltage supplies, e.g., V_PP/V_NN

+40V/–160V, +100V/–100V and +160V/–40V.

• Medical Ultrasound Imaging

• Non-Destructive Testing Metal Flaw Detection

• Piezoelectric Transducer Drivers

• Inkjet Printer Heads

• Optical MEMS Modules
