1-12-2000 | The LT1783 rail to rail opamp is an exceedingly robust device. It has reverse battery protection up to 18 V, a common mode input voltage of...

1-07-2000 | The sound generator shown here uses its built-in loudspeaker as a microphone when it is in the standby state. As soon as it detects a noise...

1-07-2000 | A symmetrical ±5 V power supply is often needed for small, battery-operated operational amplifier projects and analogue circuits. An IC that...

1-07-2000 | The Philips Semiconductors TDA8551 is a small audio amplifier with an integrated volume control. When operated from +5 V, it delivers a nomi...

1-07-2000 | Nowadays, it is no longer necessary to use discrete components to build oscillators. Instead, many manufacturers provide ready-made voltage-...

1-07-2000 | Anyone who has to reduce the amplitudes of RF signals in a controlled manner needs an attenuator. Linearly adjustable attenuation networks u...

1-07-2000 | If you want to connect a video signal to several destinations, you need a distribution amplifier to match the 75-ohm video cable. A distribu...

1-07-2000 | Contact bounce is an age-old problem with all types of pushbutton switches and keypads that are connected to digital components. The measure...

1-07-2000 | Transistors are often used for switching power supply voltages. MOSFETs are most often used, since they have low ‘on’ resistances, and they...

1-04-2000 | Maxim has recently introduced a new integrated current meter IC called the MAX4173. It converts a current measured in the positive supply le...
