ABLIC S-US55D2

The ABLIC S-US55D2 is an octal, 12-bit, 200MSPS, Digital-to-Analog Converter (DAC) with analog differential outputs and 2-bit per channel CMOS output pattern generators. It is designed for an ultrasound linear amplifier with 3-level pulser (3LP). Each channel has a 12bit x 4096 DAC pattern memory and a 128Byte 3LP pattern memory. The S-US55D2 is suitable as the input signal pattern generator to the S-UM55L2 ultrasound transmitter.
