00 — Overview

What the LM158DR family does

The LM158 is a dual operational amplifier featuring two independent, internally compensated high-gain amplifiers in a single package. It supports single or dual power supply operation with a range of 3 to 32 V and operates across industrial temperatures from -40 to 105 °C. Key specifications include a typical input offset voltage of 2 mV, input bias current of 45 nA, and a large signal voltage gain of 50 V/mV. The device offers high common-mode rejection of 85 dB and power supply rejection of 100 dB. Available in DIP8 or SOP8 packages, the LM158 serves applications such as frequency converters, DC gain blocks, and standard operational amplifier circuits.
