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 (R

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.
