13V/µs slew rate — what it buys you
A 13V/µs slew rate means this op-amp can swing a 10 V peak-to-peak output at frequencies up to roughly 200 kHz before the output becomes slew-rate limited. For audio line-level signals (typically 2 V p-p), the full bandwidth extends well into the hundreds of kilohertz, making it a good fit for audio preamplifiers, active filters, and signal conditioning stages where preserving signal edges matters.
Supply range and current — design margin notes
The TL072BCPG4 operates from a total supply span of 10 V to 30 V, which accommodates common ±5 V, ±12 V, and ±15 V split rails. At 1.4 mA total supply current for both amplifiers, the quiescent power dissipation stays under 50 mW on ±15 V rails — low enough that the 8-PDIP package does not need heatsinking in normal ambient conditions.
