Rohm Semiconductor's BD14210G-LA current sense amplifier IC simplifies current sensing by connecting a shunt resistor and a bypass capacitor, which reduces the number of components from 11 to just three compared to conventional configurations.
Decreases the mounting area by 46% (SSOP6 package) and achieves current detection of ±1% over the entire temperature range (-40°C to +125°C). Internal circuitry prevents current detection accuracy from decreasing even when an external RC filter circuit for noise suppression is added. Features wide input voltage range (-0.2V to +26V) making it ideal for current sensing applications operating from 12V/24V power supplies. BD1421x-LA series will include a total of eight models, featuring both single-channel and dual-channels variants in four different gain settings (20, 50, 100, 200V/V).
