HV2605 Low Harmonic Distortion 16-Channel High Voltage Analog Switch Features General Description HVCMOS technology for high performance The Supertex HV2605 is a low charge injection 16-channel high 16-channel high voltage analog switch voltage analog switch integrated circuit (IC) intended for use in 3.3V input logic level compatible applications requiring high voltage switching controlled by low 20MHz data shift clock frequency voltage control signals, such as medical ultrasound imaging and Very low quiescent power dissipation (-10A) other piezoelectric transducer drivers. Low parasitic capacitance DC to 50MHz small signal frequency response Input data are shifted into a 16-bit shift register that can then -60dB typical off-isolation at 5.0MHz be retained in a 16-bit latch. To reduce any possible clock feed CMOS logic circuitry for low power through noise, the latch enable bar should be left high until all Low harmonic distortion bits are clocked in. Data are clocked in during the rising edge Cascadable serial data register with latches of the clock. Using HVCMOS technology, this device combines Flexible operating supply voltages high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. Applications The device is suitable for various combinations of high voltage Medical ultrasound imaging supplies, e.g., V /V : +40V/-160V, +100V/-100V, and +160V/- NDT metal flaw detection PP NN Piezoelectric transducer drivers 40V.
