Operational amplifier / programmable gain

The Md3872 is an eight-channel front-end collector for medical ultrasound imaging. Its outstanding low power dynamic execution is particularly suitable for convenient ultrasound provisions. The increase furthermore increase extent of the VGA could be digitally arranged independently.

The increase of the PGA could be set to one of four discrete qualities: 23.5db, 29db, 34.5db or 40db. The VCA might be persistently differed by a control voltage from -47db to a greatest of 0db. In CW mode, an incorporated trans-conductance speaker is determined by the LNA to create differential yield current. The circuit of each one channel is made out of a 14db/18db low clamor preamplifier, a voltage- controlled attenuator (VCA then again TGC), a programmable increase speaker, a hostile to associating channel (AAF) and a simple to-computerized (ADC) converter.
