Input Attenuator for the Digital Audio Millivoltmeter - If you'd like to be able to use our Digital Audio Millivoltmeter to measure AC voltages up to 140V RMS, this add-on project is the answer. It's a simple switched input divider which lets you add 40dB, 20dB or 0dB of attenuation ahead of the meter at the touch of a knob. __ SiliconChip

Op Amp linearizes attenuator control response - 07/25/02 EDN-Design Ideas Professional-audio equipment commonly uses Analog Devices'(www.analog.com] high-performance, quad-voltage-controlled SSM2164 attenuator. The control response is -30 dB/V, with 0V producing unity gain. Attenuation increases as the applied control voltage increases in the positive direction. The circuit in Figure 1 extends the range of applications for this versatile chip by providing a simple__ Circuit Design by Mike Irwin, Shawville, PQ, Canada
Passive Attenuator - This attenuator was the result of a search for an inexpensive attenuator which could be used on an HT to help beginners equip themselves for a hidden transmitter hunt. The 3/8 inch piece of wire will extend into the center conductor of the bulkhead adaptor forming a small capacitor. The coupling between the two conductors will vary as the PL-259 shell is turned further onto the bulkhead adaptor. __ Contact: Joe Leggio WB2HOL

Precision divide-by-two analog attenuator needs no external components - 03/17/05 EDN-Design Ideas Many modern A/D converters offer only a 5V input range, and using these converters with a 65V or larger input signal gives the designer a problem how to discard half of a good analog signal without introducing errors and distortion. To solve the problem, you can use an attenuator comprising two operational amplifiers and two resistors(Figure 1)__ Circuit Design by Moshe Gerstanhaber and Chau Tran, Analog Devices, Wilmington, MA
