●Product Details
●The ADA4960-1 is a high performance, differential amplifier optimized for RF and IF applications. It achieves better than 63 dB IMD3 performance for frequencies up to and beyond 1 GHz, making it an ideal driver for 8-bit to 10-bit giga-sample analog-to-digital converters (ADCs).
●The buffered inputs of the ADA4960-1 isolate the gain-setting resistor (RG) from the signal inputs, maintaining a constant 10 kΩ input resistance, easing matching and input drive requirements. The ADA4960-1 has a nominal 150 Ω differential output impedance.
●The ADA4960-1 is optimized for wideband, low distortion performance for frequencies up to and beyond 1 GHz. These attributes, together with its adjustable gain capability, make this device the amplifier of choice for general-purpose IF and broadband applications where low distortion, noise, and power are critical.
●The device is optimized for the best combination of slew rate, bandwidth, and broadband distortion. These attributes allow it to drive a wide variety of ADCs. It is ideally suited for driving mixers, pin diode attenuators, SAW filters, and multi-element discrete devices.
●The user accessible gain adjust and bandwidth extension features allow configuration of the ADA4960-1 for line driver and channel equalization applications.
●The quiescent current of the ADA4960-1 is typically 60 mA. When disabled, it consumes less than 3 mA, offering excellent input-to-output isolation.
●Fabricated on an Analog Devices, Inc., high speed SiGe process, the ADA4960-1 is available in a compact 3 mm × 3 mm, 16-lead LFCSP. It operates over the temperature range of −40°C to +85°C.
