MC33501, MC33503 1.0 V, Rail−to−Rail, Single Operational Amplifiers The product is a single supply operational amplifier that provides rail−to−Rail operation on both the input and output, and the output voltage can swing within 50 mV of each power rail. It has high input impedance, high output current and low input offset
The MC33501 and MC33503 are low‑voltage, single‑supply operational amplifiers that operate from 0.9 V up to 7 V and feature rail‑to‑rail input and output. They are designed for portable and battery‑powered applications, offering high input impedance and low supply current.
Key features include up to 40 mA output drive at 5 V, a typical unity‑gain bandwidth of 4 MHz at 5 V, and operation over an extended temperature range of –40 °C to 105 °C. The devices are available in a compact SOT23‑5 package with detailed pin‑out and marking information.
