LMH6523SQE/NOPB Product Details
The LMH6523SQE/NOPB 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 LMH6523SQE/NOPB 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 LMH6523SQE/NOPB 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 enable pin is active in both serial and parallel modes for systems that require high speed power control.
The LMH6523SQE/NOPB 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.
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 a wide range filter designs or analog to digital converters. For applications which have very large changes in signal level LMH6523SQE/NOPB can support up to 62dB of gain range by cascading channels.
The LMH6523SQE/NOPB operates over the industrial temperature range of 40°C to 85°C. The LMH6523SQE/NOPB is available in a 54-Pin, thermally enhanced, LLP package.
