Double The Output Current To A Load With The Dual OPA2604 Audio Op Amp
PDF, 21 Kb, File published: Sep 27, 2000
Headphones typically have an impedance of 40О© to 300О©. By using the dual OPA2604 and four resistors one can economically drive a 2.8V peak signal into the 40О© headphones.

A Low Noise, Low Distortion Design for Antialiasing and Anti-Imaging Filters
PDF, 62 Kb, File published: Sep 27, 2000
In any digitizing system, antialiasing and anti-imaging filters are used to prevent the signal frequencies from folding back around the sample frequency and causing false (or alias) signals from appearing in the signal we are attempting to digitize. Very often, these filters must be very complex, high order analog filters in order to do their job effectively.

Tuning in Amplifiers
PDF, 44 Kb, File published: Oct 2, 2000
Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket?
