source driver. It is designed for medical ultrasound imaging and
HIFU beamforming applications. It also can be used in NDT,
Sonar and other ultrasound phase-array focusing beamforming
applications.
The MD2131 consists of CMOS digital logic input circuits, an
8-bit current DAC for waveform amplitude control, and four PWM
current-sources. These current sources are constructed with the …
