STHVUP64

STHVUP64 64-Channel Ultrasound Transmitter

STMicroelectronics STHVUP64 64-Channel Ultrasound Transmitter is a monolithic, high-voltage/high-speed pulse generator featuring 64x independent channels integrating a 64-channel beamformer for pulse generation. The STHVUP64 targets multi-channel medical ultrasound applications, specifically low-power ultra-portable systems. A pure analog section provides each channel two half-bridges (two high-voltage P-channel and two high-voltage N-channel MOSFETs), a clamping-to-ground circuit, and a transmitting/receiving switch structure which guarantees effective isolation during the transmission phase. Each channel also features integrated high-voltage level translators, noise-blocking diodes, and an anti-leakage circuit.
