AD8370 Datasheet PDF

●The AD8370AREZ is a digitally controlled Variable Gain Amplifier (VGA) provides precision gain control, high IP3 and low noise figure. The excellent distortion performance and wide bandwidth make the AD8370 a suitable gain control device for modern receiver designs. For wide input, dynamic range applications, the AD8370 provides two input ranges - high gain mode and low gain mode. A vernier, 7-bit, transconductance (gm) stage provides 28dB of gain range at better than 2dB resolution and 22dB of gain range at better than 1dB resolution. A second gain range, 17dB higher than the first, can be selected to provide improved noise performance. The AD8370 is powered on by applying the appropriate logic level to the PWUP pin. When powered down, the AD8370 consumes less than 4mA and offers excellent input to output isolation. The gain setting is preserved when operating in a power-down mode.
