TL072CDT

TL072CDT is the tape-and-reel SO-8 ordering code for the STMicroelectronics TL072 dual JFET-input operational amplifier; ST’s product quality table lists the TL072CDT code as Active in the SO-8 package. The C in the code is the commercial temperature grade, 0 °C to +70 °C — the wider-range I grade is a different ordering code, and its range must not be read onto this one. Read on ST’s own electrical table: slew rate of 8 V/µs minimum and 16 V/µs typical, gain-bandwidth of 2.5 MHz minimum and 4 MHz typical, input noise of 15 nV/√Hz typical at 1 kHz, harmonic distortion of 0.01 % typical, on a total supply of up to 36 V. The selection point is the JFET input stage: very high input impedance and picoamp-class bias current for high-impedance sources — photodiodes, piezo sensors, sample-and-hold circuits and audio front ends — at a jelly-bean cost. Selection advice: every figure on this page is ST’s; the Texas Instruments TL072 is a different maker’s part whose published numbers differ, so qualify the ST code against the ST datasheet (DocID2298) rather than against a generic TL072 listing. Parameters verified against the ST TL072 datasheet and the ST product page.
