LMH6517 Low Power, Low Noise, IF and Baseband, Dual 16 bit ADC Driver With Digitally Controlled Gain
General Description
The LMH6517 contains two high performance, digitally controlled variable gain amplifiers (DVGA).

It has been designed for use in narrowband and broadband IF sampling applications. Typically the LMH6517 drives a high performance ADC in a broad range of mixed signal and digital communication applications such as mobile radio and cellular base stations where automatic gain control (AGC) is required to increase system dynamic range. Each channel of LMH6517 has an independent, digitally controlled attenuator and a high linearity, differential output amplifier. Each block has been optimized for low distortion and maximum system design flexibility. Each channel can be individually disabled for power savings. The LMH6517 digitally controlled attenuator prov
