Input bias current of 15 nA typical means the voltage error across a 10 kΩ source resistor is 150 µV — negligible for most applications, but a high-impedance source above 100 kΩ will see a noticeable offset that may require a lower-bias op-amp. Supplied in tube packaging, suitable for low-volume assembly or prototyping; for reel-fed production, order the tape-and-reel variant if available. RoHS3 compliant (ROHS3), meeting the latest EU restriction directive for lead and other hazardous substances.","metaTitle":"STMicroelectronics TS921ID Op-Amp, 4 MHz GBW, Rail-to-Rail","metaDescription":"TS921ID general-purpose op-amp: 4 MHz GBW, 1.3 V/µs slew rate, rail-to-rail output, 2.7-12 V supply, -40 to 125 °C.
