Description

The HV2605 and HV2705 are 16-channel low

harmonic distortion high-voltage analog switch

integrated circuits (ICs). These devices are designed

for applications requiring high-voltage switching

controlled by low-voltage control signals, such as

medical ultrasound imaging and other piezoelectric

transducer drivers. The HV2705 has integrated bleed

resistors which eliminate voltage build-up on capacitive

loads such as piezoelectric transducers.

These ICs shift input data 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 are

clocked in during the rising edge of the clock. This

device combines high-voltage, bilateral DMOS

switches and low-power CMOS logic to provide

efficient control of high-voltage analog signals.

The device is suitable for various combinations of highvoltage

supplies, e.g., VPP/VNN: +40V/–160V,

+100V/–100V and +160V/–40V.
