LMH6517SQ Product Details

The LMH6517SQ 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 LMH6517SQ 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 LMH6517SQ 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 LMH6517SQ digitally controlled attenuator provides precise 0.5dB gain steps over a 31.5dB range. On chip digital latches are provided for local storage of the gain setting. Both serial and parallel programming options are provided. A Pulse mode is also offered where simple up or down commands can change the gain one step at a time.

The output amplifier has a differential output allowing large signal swings on a single 5V supply. The low impedance output provides maximum flexibility when driving filters or analog to digital converters.

The LMH6517SQ operates over the industrial temperature range of 40°C to +85°C. The LMH6517SQ is available in a 32-Pin, thermally enhanced, WQFN package.
