Product Details
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, surface acoustic wave (SAW) filters, and multielement 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.

Tools & Simulations
Sys-Parameters
Sys-Parameter Models for Keysight Genesys
Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.
Design Tools
ADIsimPLL™
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimRF
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
