HX6002-S

The HX6001-ST/HX6002-S/HX6004-S family of operational amplifiers, including single-, dual-, and quad- channel options, is specifically designed for cost-sensitive systems and applications. These amplifiers feature rail-to-rail input and output swings, low quiescent current (typically 75 μA), wide bandwidth (1.5 MHz), and very low noise (25 nV/√Hz at 1 kHz), making them highly suitable for battery-powered applications that require a balance between cost and performance. Examples of such applications include audio outputs, consumer electronics, smoke detectors, portable medical devices, and white goods. The low input bias current allows these amplifiers to be used with high impedance sources. The robust design of the HX6001-ST/HX6002-S/HX6004-S amplifiers offers ease-of-use for circuit designers, with unity-gain stability even with capacitive loads up to 500 pF, integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high electro-static discharge (ESD) protection (5-kV HBM). The HX6001-ST/HX6002-S/HX6004-S amplifiers are optimized for operation at voltages ranging from +1.8 V (±0.9 V) to +5.5 V (±2.75 V) within a temperature range of 0 °C to 70 °C. They can also operate at voltages from +2.0 V (±1.0 V) to +5.5 V (±2.75 V) over an extended temperature range of -40 °C to +125 °C.
