LMH2832 Digital Variable Gain Amplifier (DVGA)
Texas Instruments LMH2832 Digital Variable Gain Amplifier (DVGA) is a high-linearity, dual-channel, digital variable gain amplifier for high-speed signal chain and data-acquisition systems. The LMH2832 is optimized to provide high bandwidth, low distortion, and low noise. This optimization makes this device ideally suited as a dual, 14-bit, analog-to-digital converter (ADC) driver. The device consists of one fixed-gain block and one variable attenuator consisting of a total gain of 30dB with a maximum attenuation of 39dB. The gain range is from 30dB to -9dB in 1dB gain steps with a gain accuracy of ±0.2dB. The Texas Instruments LMH2832 is designed to drive general-purpose ADCs and meets both data over cable service interface specifications (QAM and OFDM systems). With excellent NF (6.5 dB) and linearity, the LMH2832 is designed to perform within DOCSIS specifications.
