Low Distortion Differential RF/IF Amplifier
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.Availability

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
AD8351-EVALZ is a fully populated, 4-layer, FR4-based evaluation board designed to allow easy evaluation of all features of the AD8351. The evaluation board integrates bypassable transformers to allow single ended or differential inputs and output, place holders for an impedance matching network and the evaluation board requires only a single supply within the range of 3.0 V to 5.5 V.
