Product Overview
The HV2701FG-G is a 16-channel high-voltage analog switch IC from Microchip for medical ultrasound and industrial flaw detection equipment. It adopts high-voltage CMOS technology supporting ±100V analog signals, featuring low on-resistance and low parasitic capacitance. Each channel integrates bleed resistors to eliminate transducer residual charge noise. Equipped with serial shift register control, it easily connects with FPGA/MCU, and the 48-LQFP 7×7mm lead-free package saves PCB space for multi-channel probe equipment.
Core Advantages
16-Channel High-Density Integration
16 independent high-voltage switches in one chip, simplifying PCB layout and cutting multi-channel device BOM costs.
Built-in Bleed Resistor Network
On-channel bleed resistors quickly release transducer residual voltage, preventing equipment damage and signal noise.
Excellent Signal Integrity & Low Distortion
Low on-resistance and tiny parasitic capacitance reduce crosstalk and waveform distortion during high-frequency pulse transmission.
Wide High-Voltage Input Range
Supports ±100V analog rail, compatible with all mainstream ultrasonic piezoelectric drive circuits.
