The LMV324IDR is a quad low-voltage rail-to-rail output operational amplifier from TI/ST in SOIC-14, operating from 2.7V to 5.5V with 1.1MHz gain-bandwidth product and 1V/us slew rate. It is the low-voltage version of the industry-standard LM324, maintaining pin compatibility while extending operation down to 2.7V. The output stage swings to within 50mV of the rails with a 10k-ohm load (rail-to-rail output), but the input common-mode range extends only to VCC-1V (not rail-to-rail input). The supply current is 130uA per amplifier, giving a GBW-to-Iq ratio of 8.5kHz/uA. The input bias current is 45nA typical, and input offset voltage is 1.7mV typical. The device is designed for single-supply operation: the GND pin (pin 11) replaces the V- pin of the LM324, and the input common-mode range includes ground (0V), making it suitable for ground-referenced signal conditioning. The 1.1MHz GBW supports active filters up to approximately 100kHz. Each amplifier is independent, allowing different configurations per channel (inverting, non-inverting, comparator). The -IDR suffix specifies SOIC-14, industrial temperature range (-40C to +85C), tape-and-reel. Applications include battery-powered signal conditioning, sensor interfaces, and portable medical equipment.
