Why use two individual VGAs when the Analog Devices AD8376 digital VGA gives you dual channels in 67% less space? Analog Devices' industry-leading solution offers 50 dBm output IP3 on just 130 mA of current per channel, providing unparalleled linearity and minimizing distortion. You can maximize signal level prior to the ADC across a broad choice of IFs up to 400 MHz, while reducing your footprint with the AD8376's compact, 5 mm × 5 mm 32-lead LFCSP package. For applications requiring additional gain control range, such as upstream CMTS receivers, ADI's AD8372 VGA offers 41 dB of range in 1 dB steps. more ...

AN-737: How ADIsimADC™ Models an ADC (pdf, 291,797 bytes)
Converter modeling has often been overlooked, omitted, or accomplished using an ideal data converter model. With more and more systems using mixed-signal technology, the importance of system modeling is ever increasing. Coupled with shortened design cycles and pressure for fi rst pass success, this drives the continuing importance of complete system modeling. ADIsimADC has been developed to answer this growing need.
