Overview
The LM158YDT is a low-power dual operational amplifier produced by STMicroelectronics. It is part of the LM158 series, which includes the LM158, LM258, and LM358 models. These operational amplifiers are designed to operate from a single power supply over a wide range of voltages, making them versatile for various applications.
The LM158YDT features two independent, high-gain, internally frequency-compensated op-amps. This design allows for operation in single power supply systems, eliminating the need for dual supplies and enabling direct sensing near ground and output voltage swings to ground.
