AD8351: Low Distortion Fully Differential RF / IF Amplifier
Product Description
The AD8351 is fully differential amplifier, designed to drive high resolution (10-14 bits) / high speed ADCs (240 MSPS) at IF frequencies within communications receivers.
The AD8351 simplifies ADC driving allowing the user to adjust the gain (up to 26 dB) through one external resistor and incorporates output common mode adjustment circuit to ease the drive levels into the ADC.
The AD8351 is a very low distortion gain stage, along with low noise and wide gain bandwidth, making the part ideally suited to be used in digital communications IF receivers. The part has been fully specified for operation at a number of common IF frequencies 70/140/240 MHz.
The AD8351 product data sheet provides detailed circuits on the driving 12-/14-bit resolution ADCs and using the device for single ended to differential signal conversion.
The AD8351 is fabricated on an advanced silicon bipolar process, operating on a single 3 or 5 volt supply, packaged in space saving 10-lead micro SOIC package and fully specified over the –40ºC to +85ºC temperature range.
