AD8005ARTZ-REEL7

The AD8005 is an ultralow power, high speed amplifier with a wide signal bandwidth of 170 MHz and slew rate of 280 V/μs. This performance is achieved while consuming only 400 μA of quiescent supply current. These features increase the operating time of high speed battery powered systems without reducing dynamic performance. The current feedback design results in gain flatness of 0.1 dB to 30 MHz while offering differential gain and phase errors of 0.11% and 0.4°. Harmonic distortion is low over a wide bandwidth with THDs of -63 dBc at 1 MHz and -50 dBc at 10 MHz. Ideal features for a signal conditioning amplifier or buffer to a high speed A-to-D converter in portable video, medical or communication systems. The AD8005 is characterized for +5 V and ±5 V supplies and operates over the industrial temperature range of -40°C to +85°C. The amplifier is supplied in 8-lead PDIP, 8-lead SOIC_N, and 5-lead SOT-23 packages.
