DATASHEET EL8176 FN7436 Rev 9.00 Micropower Single Supply Rail-to-Rail Input/Output Precision Op Amp January 6, 2015 The EL8176 is a precision low power, operational amplifier. Features The device is optimized for single supply operation between 55A supply current 2.4V to 5.5V. 100V max offset voltage (8 Ld SO) The EL8176 draws minimal supply current while meeting excellent DC-accuracy noise and output drive specifications. 2nA input bias current Competing devices seriously degrade these parameters to 400kHz gain-bandwidth product achieve micropower supply current. Single supply operation down to 2.4V The EL8176 can be operated from one lithium cell or two Ni-Cd Rail-to-rail input and output batteries. The input range includes both positive and negative Output sources 31mA and sinks 26mA load current rail. The output swings to both rails.
