It uses an SPI serial interface to set the attenuation independently for each of its two channels, making it a direct drop-in for processor-controlled preamplifier stages, mixing consoles, and head-unit audio paths. ## Lifecycle and sourcing — active, no LTB risk That means no last-time-buy deadline to manage and no forced redesign for the foreseeable future. The part is RoHS non-compliant (lead-bearing), so verify your assembly line's exemption status if you are shipping into RoHS-regulated markets.","metaTitle":"LM1972M Volume Control IC, SPI, 20-SOIC, Active","metaDescription":"LM1972M stereo volume control IC with SPI interface in 20-SOIC. 4.5V-12V supply, 0-70°C.
