The AD8375 is a 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 AD8375 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 AD8375 achieves 50 dBm output IP3 at 200 MHz.
The AD8375 provides a broad 24 dB gain range with 1 dB resolution. The gain is adjusted through a 5-pin control interface 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.
The AD8375 is powered on by applying the appropriate logic level to the PWUP pin. The quiescent current of the AD8375 is typically 130 mA. When powered down, the AD8375 consumes less than 5 mA and offers excellent input-to-output isolation.
Fabricated on an Analog Devices, Inc., high speed SiGe process, the AD8375 is supplied in a compact, thermally enhanced, 4 mm × 4 mm, 24-lead LFCSP package and operates over the temperature range of −40°C to +85°C.

Tools & Simulations
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.
Open ToolADIsimRF
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.
Open ToolADIsimPLL™
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.
