The AD8351 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 provides a nominal 150 Ω differential output impedance. The excellent distortion performance and low noise characteristics of this device allow for a wide range of applications.
The AD8351 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 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 an ideal solution for 12-bit and 14-bit IF sampling receiver designs.
Fabricated in Analog Devices, Inc., high speed XFCB process, the AD8351 has high bandwidth that provides high frequency performance and low distortion. The quiescent current of the AD8351 is 28 mA typically. The AD8351 amplifier comes in a compact 10-lead MSOP package or in a 16-lead LFCSP package, and operates over the temperature range of −40°C to +85°C.
