The AD8351-EP is a low cost differential amplifier useful in RF and IF applications up to 2.2 GHz. The voltage gain can be set from unity to 26 dB using a single external gain resistor. The AD8351-EP provides a nominal 150 Ω differential output impedance. The excellent distortion performance and low noise characteristics of this device allow a wide range of applications.

The AD8351-EP is designed to satisfy the demanding performance requirements of communications transceiver applications. The device can be used as a general-purpose gain block, an ADC driver, and a high speed data interface driver,among other functions. The AD8351-EP can also be used as a single-ended-to-differential amplifier with similar distortion products as in the differential configuration. The exceptionally good distortion performance makes the AD8351-EP an ideal solution for 12-bit and 14-bit IF sampling receiver designs.

Fabricated in the Analog Devices, Inc., high speed XFCB process, the AD8351-EP has a high bandwidth that provides high frequency performance and low distortion. The quiescent current of the AD8351-EP is 28 mA typically. The AD8351-EP amplifier comes in a 16-lead LFCSP package, and operates over the temperature range of −55°C to +105°C.
