AD8033:  Very Low-Cost High-Speed FastFET™ Op Amps

Product Details


The AD8033 FastFET amplifier is a voltage feedback amplifier with FET inputs, offering ease of use and excellent performance. The AD8033 FastFET op amp in ADI's proprietary XFCB process offers significant performance improvements over other low cost FET amps, such as low noise (11 nV/√Hz and 0.6 fA/√Hz) and high speed (80 MHz bandwidth and 80 V/µs slew rate).

With a wide supply voltage range from 5 V to 24 V and fully operational on a single supply, the AD8033 amplifier will work in more applications than similarly priced FET input amps. In addition, the AD8033 has rail-to-rail outputs for added versatility.

So far most clamping amplifiers have relied upon an output clamping architecture and are called output clamp amps (OCAs). A new architecture called an input clamp amp (ICA) offers superior clamping accuracy and lower distortion.
Application Notes PDF
AN-417: Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High Speed Systems  (pdf, 228 kB)
Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits.
