      2. Description

       The EG8543 is a dual operational amplifier with low operating current, single supply, 4 MHz bandwidth and high speed rail-to-rail input and output. Rail-to-rail input and output allows designers to implement ASIC buffering in a single power supply system. The EG8543 is optimized for high gain at lower supply voltages and can therefore be used for active and gain stages. 
  The EG8543 has a very low input bias current and can be used in integrators, photodiode amplifiers, piezoelectric sensors, and other applications with higher source impedances. Each amplifier power supply current is only 200uA, very suitable for battery-powered applications. The EG8543 is specified over the extended industrial temperature range from -40 ° C to + 125 ° C. The EG8543 is available in an 8-pin SOIC surface mount package. Package.
