HX9002-S

The HX9002-S family of operational amplifiers, including single-, dual-, and quadchannel 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 (1MHz), 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. The low input bias current allows these amplifiers to be used with high impedance sources. The robust design of the HX9002-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 HX9002-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.
