ADA4961ACPZN-R7

ADA4961 is a high performance, BiCMOS RF digital gain amplifier (DGA), optimized for driving heavy loads out to 2GHz and beyond. This device typically achieves -90dBc IMD3 performance at 500MHz and -85dBc at 1.5 GHz. This RF performance allows GHz converters to achieve their optimum performance with minimal limitations of the driver amplifier or constraints on overall power that typically result from GaAs amplifiers. This device can easily drive 10bit to16bit HS converters. For many receiver applications, antialias filter (AAF) designs can be simplified or not required. It has an internal differential input impedance of 100 ohm and a differential dynamic output impedance of 50 ohm, eliminating the need for external termination resistors. It is used in applications such as ADC driver for 10bit to 14bit GSPS converters, RF/IF gain blocks, line drivers, instrumentation, satellite communications, data acquisition, military systems.
