The AD8515 is a rail-to-rail amplifier that can operate from a single-supply voltage as low as 1.8 V. The AD8515 single amplifier, available in SOT-23-5L and SC70-5L packages, is small enough to be placed next to sensors, reducing external noise pickup. The AD8515 is a rail-to-rail input and output amplifier with a gain bandwidth of 5 MHz and typical offset voltage of 1 mV from a 1.8 V supply. The low supply current makes these parts ideal for battery-powered applications. The 2.7 V/s slew rate makes the AD8515 a good match for driving ASIC inputs, such as voice codecs.
