Norwood, MA — August 26, 2004 — Analog Devices has introduced an operational amplifier that combines an easy-to-use voltage-feedback architecture, unity-gain stability, and pin-out optimized for ...

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

Two high-speed, voltage-feedback op amps from Micrel - MIC920 and MIC921 - provide an order of magnitude improvement in the ratio of slew rate-to-power consumption, compared with competing devices.

Michael Steffes challenges conventional approaches to Sallen Key Filter design. He says today's components and VFAs offer greater flexibility. This opinion piece links to more detailed explanations.

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...
