VCA8617: Response to Step-Change in Gain Control
PDF, 102 Kb, 档案已发布: Mar 24, 2005
The VCA8617 is an 8-channel variable gain amplifier ideally suited for portable and mid-range ultrasound applications. Each channel consists of a Low Noise Amplifier (LNA) and a Variable Gain Amplifier (VGA). The VGA contains two parts: a voltage-controlled attenuator (VCA) and a programmable gain amplifier (PGA). The PGA output feeds directly into an integrated 3-pole low-pass Butterworth filter.
