With a 15 MHz gain-bandwidth product and 7 V/µs slew rate, it handles audio-band signals up to several hundred kilohertz with minimal phase shift — sufficient for active filters, preamplifiers, and equalizer stages in professional and consumer audio equipment. ## Quad density in a 14-SOIC footprint Four amplifiers in one 14-SOIC (3.90 mm width) package saves board area compared to using two dual op-amps or four single op-amps. Each channel can deliver 37 mA output current — enough to drive line-level audio loads or headphone buffers with modest impedance. ## Supply headroom and input characteristics The TS524IDT operates from a single supply as low as 5 V up to 30 V, or from dual supplies of ±2.5 V to ±15 V. Input bias current is 250 nA (typical), and input offset voltage is 950 µV — adequate for AC-coupled audio paths where DC precision is secondary to bandwidth and noise performance. Supply current per device is 8 mA, which keeps the total power dissipation manageable in a 14-SOIC package even at elevated temperatures.","metaTitle":"STMicro TS524IDT Audio Quad Op-Amp, 15 MHz, 7 V/µs","metaDescription":"STMicroelectronics TS524IDT audio quad op-amp: 15 MHz GBW, 7 V/µs slew rate, 14-SOIC, -40°C to 125°C.
