Description
General part information
LMH6522 Series
The LMH6522 contains four, high performance, digitally controlled variable gain amplifiers (DVGA). It has been designed for use in narrowband and broadband IF sampling applications. Typically, the LMH6522 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 LMH6522 has an independent, digitally controlled attenuator and a high linearity, differential output, amplifier. All circuitry has been optimized for low distortion and maximum system design flexibility. Power consumption is managed by a three-state enable pin. Individual channels can be disabled or placed into a Low Power Mode or a higher performance, High Power Mode.
The LMH6522 digitally controlled attenuator provides precise 1dB gain steps over a 31dB range. The digital attenuator can be controlled by either a SPI Serial bus or a high speed parallel bus.
