LM1972M/NOPB产品概述

The LM1972M/NOPB is a Micro-Pot 2-channel Audio Attenuator with mute fabricated on a CMOS process. Each channel has attenuation steps of 0.5dB from 0dB to 47.5dB, 1dB steps from 48dB to 78dB, with a mute function attenuating 104dB. Its logarithmic attenuation curve can be customized through software to fit the desired application. The performance of a μPot is demonstrated through its excellent Signal-to-Noise Ratio, extremely low (THD+N) and high channel separation. Each μPot contains a mute function that disconnects the input signal from the output, providing a minimum attenuation of 96dB. Transitions between any attenuation settings are pop free. The LM1972's 3-wire serial digital interface is TTL and CMOS compatible, receiving data that selects a channel and the desired attenuation level. The Data-Out pin of the attenuator allows multiple μPots to be daisy-chained together, reducing the number of enable and data lines to be routed for a given application.
