AD8432-EVALZ

双通道超低噪声放大器，具有可选择的增益和输入阻抗 Dual-Channel Ultralow Noise Amplifier with Selectable Gain and Input Impedance

The is an evaluation board for AD8432 device. The AD8432 is a dual channel, low power, ultralow noise amplifier with selectable gain and active impedance matching. Each channel has a single ended input, differential output and integrated input clamps. The AD8432 evaluation board is completely assembled and pretested, the board provides convenient and fast verification of system design and to assess the performance of the AD8432 under user specific operating conditions. The board provides access to the inputs, the outputs and the gain settings. As shipped, the board is configured for a gain of 21dB and 50ohm input termination. Multiple combinations of gain and impedance matching are available to the user. The AD8432 features active input termination, the input impedance is determined by the LNA gain, and the feedback resistors and source impedance.
