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 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 Continuous-Time-Sigma-Delta (CTΣΔ) architecture with digital decimation filtering to maximize dynamic performance and provide an alias free input bandwidth to ADC CLK / 2. The ADC digital outputs are serialized and provided on differential LVDS outputs. The ADC includes an on-chip clock cleaner PLL.
In addition, for baseband CW Doppler Beamformer applications, an 8-channel demodulator with 16 discrete phase rotation angles is included.
Selective power reduction is included to minimize consumption of idle sections during interleaved imaging modes.
An SPI™ compatible serial interface allows dynamic digital programming and control. Texas Instruments offers a full development package for sale which includes acquisition analysis hardware and software with user friendly GUI for device programming and control.
