  • AD8432- Dual-Channel Ultralow Noise Amplifier with Selectable Gain and Input Impedance
    AD8432: Dual-Channel Ultralow Noise Amplifier with Selectable Gain and Input Impedance

    The AD8432 is a dual-channel, low power, ultralow noise amplifier with selectable gain and active impedance matching. Each amplifier has a single-ended input, differential output, and integrated input clamps. By pin strapping the gain setting pins, four accurate gains of G = 12.04 dB, 18.06 dB, 21.58 dB, and 24.08 dB (×4, ×8, ×12, and ×16) are possible. A bandwidth of 200 MHz at G = 12.04 dB makes MoreRead more
