HV2809 Supertex inc. Low Harmonic Distortion, 32-Channel, High Voltage Analog Switch Relay Replacement IC General Description Features The Supertex HV2809 is a low harmonic distortion, 32-channel, high 32-channel high voltage analog switch voltage analog switch integrated circuit (IC), designed for use in medical 2:1 multiplexer/demultiplexer ultrasound imaging systems as a probe selection relay replacement. Enable control for all-OFF state It serves as a 16PDT (16-pole, double throw) high voltage analog 3.3 or 5.0V CMOS input logic level switch array. The enable function allows the parts to be configured HVCMOS technology for high performance as either a 2:1 or 4:1 multiplexer/demultiplexer. The HV2809 is a very Very low quiescent power dissipation, 10A fast transducer multiplexer that consumes minimal power and emits Low parasitic capacitance no audible noise. DC to 50MHz analog signal frequency Using HVCMOS technology, this device combines high voltage bilateral -60dB typical OFF-isolation at 5.0MHz DMOS switches and low power CMOS logic to provide efficient control CMOS logic circuitry for low power of high voltage analog signals. Excellent noise immunity Flexible operating supply voltages The device is suitable for various combinations of high voltage 56-Lead 8x8 QFN package supplies, e.g., V /V : +40V/-160V, +100V/-100V, and +160V/-40V. PP NN Applications The HV2809 comes in an 8.0mm x 8.0mm x 1.0mm, 56-Lead QFN Electromechanical relay replacement in package. Compared to an electromechanical relay, it not only saves medical ultrasound probes. considerable PCB area, but also saves on the PCB assembled height.
