Description

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.

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 are clocked in during the rising edge of the clock. Using HVCMOS technology, this device HV2701 combines high voltage bilateral DMOS  switches and low power CMOS logic to provide effi cient control of high voltage analog signals.

The device HV2701 is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.
