Description

The VCA2615 is a dual-channel, variable gain amplifier consisting of a Low-Noise Preamplifier (LNP) and a Variable-Gain Amplifier (VGA). This combination along with the device features makes it well-suited for a variety of ultrasound systems.

The LNP offers a high level of flexibility to adapt to a wide range of systems and probes. The LNP gain can be programmed to one of four settings (3dB, 12dB, 18dB, 22dB), while maintaining excellent noise and signal handling characteristics. The input impedance of the LNP can be controlled by selecting one of the built-in feedback resistors. This active termination allows the user to closely match the LNP to a given source impedance, resulting in optimized overall system noise performance.
