CLC5509 Ultra-Low Noise Preamplifier

The CLC5509 is a high performance, ultra-low noise preamplifier designed for applications requiring unconditional stability for wide ranges of complex input loads. Both input impedance and gain are externally adjustable, which make it simple to interface to peizoelectric ultrasound transducers. The CLC5509 preamplifier’s low 0.58nV total input noise makes it.
