LM96511 Ultrasound Receive Analog Front End (AFE)
General Description
The LM96511 is an 8-channel integrated analog front end (AFE) module for multi-channel applications, particularly medical ultrasound.
Each of the 8 signal paths consists of a low noise amplifier (LNA), a digitally programmable variable gain amplifier (DVGA) and a 12-bit, 40 to 50 Mega Samples Per Second (MSPS) analog-to-digital converter (ADC) with Instant Overload Recovery (IOR).
The architecture of the DVGA is a digitally-controlled linear-in-dB step attenuator driving a fixed-gain post-amplifier (PA).
The ADC uses a ContinuousTime-Sigma-Delta (CTΣΔ) a...
