HV2662 / HV2762 Low Harmonic Distortion, 24-Channel SPST High Voltage Analog Switch Features Description 24 Channels of high voltage analog switch HV2662/HV2762 are low-charge injection, 24-channel, 3.3 or 5.0V CMOS input logic level high-voltage analog switch integrated circuits (ICs). 24 Channel SPST configuration These ICs excel in applications requiring high-voltage switching controlled by low-voltage control signals such 20 MHz data shift clock frequency as medical ultrasound imaging, piezoelectric trans- HVCMOS technology for high performance ducer driver, and printers. HV2762 provides integrated Very low quiescent power dissipation-10A bleed resistors that eliminate voltage build-up on Low parasitic capacitance capacitive loads such as piezoelectric transducers. DC to 50 MHz analog signal frequency HV2662 does not have integrated bleed resistors. -60dB typical OFF-isolation at 5.0 MHz HV2662/HV2762 shift input data into a 24-bit shift reg- CMOS logic circuitry for low power ister that can then be retained in a 24-bit latch. To Excellent noise immunity reduce any possible clock feed through noise, the Cascadable serial data register with latches latch-enable bar should be left high until all bits are Flexible operating supply voltages clocked in during the rising edge of the clock. Using Integrated bleed resistors on outputs (HV2762 only) High Voltage CMOS technology, these ICs combine high-voltage, bilateral DMOS switches and low-power CMOS logic to provide efficient control of high voltage Applications analog signals. Medical ultrasound imaging The device is suitable for various combinations of high Piezoelectric transducer drivers voltage supplies, e.g., V /V : +40V/-160V, +100V/- PP NN Inkjet printer heads 100V, and +160V/-40V.
