Dual Inverting Log Gain/Attenuator

The DS1800 is a dual audio-taper potentiometer designed specifically for use in the feedback path of the inverting configuration of an Operational Amplifier (see Figure 2). In this configuration, the DS1800 provides a VO /VI relationship of -20log(RF/RI), giving a gain/attenuation range covering +20 dB to -63 dB. Each potentiometer has a total of 129 positions including mute. The DS1800 provides five areas of resolution, which include: 0.25 dB per step from +20 dB to +3 dB; 0.5 dB per step from +3 dB to -12 dB; 1 dB from -12 dB to -27 dB; 2 dB per step from -27 dB to -47 dB; and 4 dB per step from -47 dB to -63 dB. The mute position provides 100 dB of attenuation. By Maxim Integrated Products
