DS20005721C-page 1 HV2803/HV2903/HV2904 Features • 32-Channel, High-Voltage Analog Switch • No High-Voltage Supplies Required • 32-Channel, Single-Pole, Single-Throw (SPST) Individual Switching or Bank Switching • 3.3V CMOS Input Logic Level • 66 MHz Data Shift Clock Frequency • Silicon-on-Insulator (SOI) High-Voltage Technology for High Performance • Standby mode for Low-Power Dissipation • Low-Parasitic Capacitance • DC to 50 MHz Analog Small-Signal Frequency • 200 kHz to 50 MHz Large-Signal Frequency • -70 dB Typical Off Isolation at 5.0 MHz • Excellent Noise Immunity • Cascadable Serial Data Register with Latches • Integrated Bleed Resistors on the Outputs (both sides for HV2903, one side for HV2904) Applications • Medical Ultrasound Imaging • Nondestructive Testing (NDT) Metal Flaw Detection • Piezoelectric Transducer Drivers • Inkjet Printer Heads • Optical MEMS Modules General Description The HV2803/HV2903/HV2904 devices are low harmonic distortion, low charge injection, 32-channel, high-voltage analog switches without high-voltage supplies. They are intended for use in applications requiring high-voltage switching controlled by low-voltage control signals, such as medical ultrasound imaging, driving piezoelectric transducers and printers. The HV2903 device has integrated bleed resistors at both sides of the switches; the HV2904 device has bleed resistors at one side only, while the HV2803 device has no bleed resistors. The bleed resistor eliminates voltage build-up on capacitive loads, such as piezoelectric transducers. The HV2803/HV2903/HV2904 devices have two modes of operation determined by the MODE pin input. MODE input high enables an individual Switching mode of 32-channel SPST switches and MODE input low enables a Bank Switching mode of 16-Pole Double-Throw (16PDT) switches to support bank switching for probe selection. The devices require only ±6V or ±5V low-voltage supplies and no high-voltage supplies. However, all the analog switches can transmit ±100V high-voltage pulses.
