The EL8176 is a precision low power, operational amplifier. The device is optimized for single supply operation between 2. 4V to 5. 5V. The EL8176 draws minimal supply current while meeting excellent DC-accuracy noise and output drive specifications. Competing devices seriously degrade these parameters to achieve micropower supply current. The EL8176 can be operated from one lithium cell or two Ni-Cd batteries. The input range includes both positive and negative rail. The output swings to both rails.


  • 55μA supply current
