The AD8351 is a low cost differential amplifier useful in RF and IF applications up to 2.2 GHz. The voltage gain is programmable over a range of 0 dB to 26 dB using a single resistor. The differential interface has a low noise input stage of 2.7 nV/√Hz, –79 dBc second order harmonic distortion, –81 dBc third order harmonic distortion and a 31 dBm OIP3. It supports single supply operation (3 V to 5.5 V), low power dissipation (28 mA @ 5 V) and has an adjustable output common mode voltage, fast settling time and overdrive recovery, and a slew rate of 13,000 V/�s. The AD8351 is suitable for applications such as differential ADC drivers, single-ended to differential conversion, IF sampling receivers, RF/IF gain blocks and SAW filter interfacing.
The AD8351 is a low‑distortion differential RF/IF amplifier designed for communications transceiver applications. It offers programmable gain from 0 dB to 26 dB using a single external resistor and operates from a single 3 V to 5.5 V supply.
The device is supplied in a compact 10‑lead MSOP package, supports power‑down mode, and provides features such as low noise (2.7 nV/√Hz at 10 dB gain), high slew rate (13 000 V/µs), and wide temperature operation from –40 °C to +85 °C.
