TIDA-00822, 16-Bit, 1-GSPS Digitizer Reference Design with AC and DC Coupled Variable Gain Amplifier

TIDA-00822, 16-Bit, 1-GSPS Digitizer Reference Design with AC and DC Coupled Variable Gain Amplifier. This reference design discusses the use and performance of the Digital Variable-Gain high-speed amplifier, the LMH6401 to drive the high-speed analog-to-digital converter (ADC), the ADS54J60 device. Different options for common-mode voltages, power supplies, and interfaces are discussed and measured, including AC-coupling and DC-coupling, to meet the requirements of a variety of applications
