This datasheet introduces the features and characteristics of OP490 low voltage micropower quad operational amplifier. The amplifier supports single or dual supply operation, input voltage range includes the negative rail, single supply operation supports input signal down to ground, output swing also includes ground, enabling “zero-in, zero-out” operation. The amplifier draws less than 20 mA of quiescent supply current per amplifier, but each amplifier is able to deliver over 5 mA of output current, with extremely low power consumption and high output drive capability.
The OP490 is a high‑performance micropower quad op‑amp that can operate from a single supply of 1.6 V to 36 V or dual supplies of ±0.8 V to ±18 V. It features true single‑supply operation, low supply current (under 20 µA per amplifier), high output drive (5 mA), low offset voltage (0.5 mV max) and excellent PSRR.
The datasheet provides detailed electrical characteristics, wafer‑test limits, absolute maximum ratings, ordering information and ESD handling guidelines. Variants OP490E, OP490F and OP490G are listed with their specific parameter ranges.
