超低失真IF双通道VGA Ultralow Distortion IF Dual VGA
Product Details
The AD8376 is a dual channel, digitally controlled, variable gain wide bandwidth amplifier that provides precise gain control, high IP3, and low noise figure. The excellent distortion performance and high signal bandwidth make the AD8376 an excellent gain control device for a variety of receiver applications.
Using an advanced high speed SiGe process and incorporating proprietary distortion cancellation techniques, the AD8376 achieves 50 dBm output IP3 at 200 MHz.
The AD8376 provides a broad 24 dB gain range with 1 dB resolution. The gain of each channel is adjusted through dedicated 5-pin control interfaces and can be driven using standard TTL levels. The open-collector outputs provide a flexible interface, allowing the overall signal gain to be set by the loading impedance. Thus, the signal voltage gain is directly proportional to the load.
Each channel of the AD8376 can be individually powered on by applying the appropriate logic level to the ENBA and ENBB power enable pins. The quiescent current of the AD8376 is typically 130 mA per channel. When powered down, the AD8376 consumes less than 5 mA and offers excellent input-to-output isolation, lower than −50 dB at 200 MHz.
Fabricated on an Analog Devices, Inc., high speed SiGe process, the AD8376 is supplied in a compact, thermally enhanced, 5 mm × 5mm 32-lead LFCSP package and operates over the temperature range of −40°C to +85°C.
