GENERAL DESCRIPTION
The AD8352 is a high performance differential amplifier
optimized for RF and IF applications. It achieves better than
80 dB SFDR performance at frequencies up to 200 MHz, and
65 dB beyond 500 MHz, making it an ideal driver for high
speed 12-bit to 16-bit analog-to-digital converters (ADCs).
Unlike other wideband differential amplifiers, the AD8352 has
buffers that isolate the gain setting resistor (RG) from the signal
inputs. As a result, the AD8352 maintains a constant 3 kΩ input
resistance for gains of 3 dB to 25 dB, easing matching and input
drive requirements. The AD8352 has a nominal 100 Ω differential
output resistance.
The device is optimized for wideband, low distortion performance
at frequencies beyond 500 MHz. These attributes, together with
its wide gain adjust capability, make this device the amplifier of
choice for general-purpose IF and broadband applications
where low distortion, noise, and power are critical. It is ideally
suited for driving not only ADCs but also mixers, pin diode
attenuators, SAW filters, and multi-element discrete devices. The
device is available in a compact 3 mm × 3 mm, 16-lead LFCSP
and operates over a temperature range of 40°C to +85°C.
