This is a low power dual operational amplifier with features including internal frequency compensation, a DC voltage gain of more than 100 dB, a 1.1 mHz bandwidth (unity gain), and an extremely low supply current per operator that is essentially independent of the supply voltage. In addition, this amplifier also features low input bias current (20nA), low input offset voltage (2mV), low input offset current (2nA), input common-mode voltage range including ground, differential input voltage range equal to the power supply voltage, and a large output voltage swing of 0V to (VCC-1.5V).
The LM158, LM258 and LM358 family are low‑power dual operational amplifiers designed for single‑supply operation over a wide voltage range. They feature internally frequency‑compensated high gain, low input bias current and low offset voltage, making them suitable for transducer amplifiers and other interface circuits.
Key specifications include a supply voltage range of ±16 V to 32 V, input bias currents as low as 20 nA, output swing to within 1.5 V of the supply rail, a gain‑bandwidth product of about 1 MHz, and typical supply currents below 1 mA. Package options cover DIP‑8, SO‑8, mini‑SO‑8 and TSSOP‑8.
