With its low noise, high SFDR, and wide bandwidth, it is an ideal choice for driving analog-to-digital converters (ADCs) with resolutions to 18 bits. The AD8139 is easy to apply, and its internal common-mode feedback architecture allows its output common-mode voltage to be controlled by the voltage applied to one pin. The internal feedback loop also provides outstanding output balance as well as suppression of even-order harmonic distortion products. Fully differential and single-ended-to-differential gain configurations are easily realized by the AD8139. Simple external feedback networks consisting of four resistors determine the closed-loop gain of the amplifier.

The AD8139 is available in an 8-lead SOIC package with an exposed paddle (EP) on the underside of its body and a 3 mm × 3 mm LFCSP. It is rated to operate over the temperature range of −40°C to +125°C. 1 10 100 1k 10k 100k 1M 10M 1G 100M 10 100 FREQUENCY (Hz) Figure 3. Input Voltage Noise vs. Frequency |
