Product Details
The AD8012 is a dual, low power, current feedback amplifier capable of providing 350 MHz bandwidth while using only 1.7 mA per amplifier. It is intended for use in high frequency, wide dynamic range systems where low distortion and high speed are essential and low power is critical.
With only 1.7 mA of supply current, the AD8012 also offers exceptional ac specifications such as 20 ns settling time and 2,250 V/μs slew rate. The video specifications are 0.02% differential gain and 0.06 degree differential phase, excellent for such a low power amplifier. In addition, the AD8012 has a low offset of 1.5 mV.
The AD8012 is well suited for any application that requires high performance with minimal power.
The product is available in standard 8-lead SOIC or MSOP packages and operates over the industrial temperature range –40°C to +85°C.
Applications
- XDSL, HDSL Line Drivers
- ADC Buffers
- Professional Cameras
- CCD Imaging Systems
- Ultrasound Equipment
- Digital Cameras

Design Tools
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
