Applications
The HV2802LB-G is optimized for ultrasound transducer array front-ends where 32 independent SPST switches route high-voltage analog signals from piezoelectric elements to receive beamformers without introducing harmonic artifacts. Medical diagnostic imaging systems and high-channel-count automated test equipment (ATE) rely on this device to switch signals across ±20 V rails with minimal distortion. It is also used in industrial sonar and non-destructive testing systems where simultaneous control of 32 analog channels at high voltage is required.

Frequently Asked Questions
What supply voltage range does the HV2802LB-G support, and how many channels can be controlled simultaneously?
The HV2802LB-G supports dual supply rails up to ±20 V, enabling wide analog signal swing across all 32 SPST channels. All 32 channels can be individually controlled simultaneously, making this device suitable for ultrasound transducer arrays where each element must be switched independently. The high-voltage capability covers signal amplitudes commonly found in medical imaging and sonar front-end circuits.
How does the low harmonic distortion specification benefit ultrasound imaging system designs?
Low harmonic distortion in the HV2802LB-G ensures that received ultrasound signals passing through the 32 analog switches are not corrupted by nonlinear artifacts during the receive phase. Typical THD performance at audio and low-MHz frequencies allows the downstream receive beamformer to reconstruct tissue images with higher fidelity. This is especially critical in diagnostic imaging where signal integrity across ±20 V swing must be maintained through the switch's on-resistance path of a few tens of ohms.
When sourcing the HV2802LB-G for a new ATE design, what package form factor should engineers plan for?
The HV2802LB-G is supplied in a BGA package, which requires reflow soldering and an appropriate BGA PCB land pattern with controlled via fanout. BGA packaging achieves a significantly smaller footprint than a 32-channel device in a conventional DIP or SOIC format, often reducing board area by more than 50%. Engineers should verify ball pitch and package dimensions in the datasheet to ensure compatibility with their PCB design rules and pick-and-place equipment before placing volume orders.
