  • Description

    The NJU77572 is a dual rail-to-rail input and output single supply OpAmp featuring wide bandwidth and low noise. The combination of very low noise (9nV√Hz at 1kHz), unity-gain bandwidth (10MHz), and fast slew rate (5V/µs) make the devices ideal for a wide variety of applications, including signal conditioning and sensor amplifiers. Low input bias current, low noise and low offset voltage drift of 0.5µV/°C performances are also excellent for filters, integrators, photodiode amplifiers, and high impedance sensors. The ability of rail-to-rail input and output enables the designers to buffer ADC, DAC, and other wide output swing devices in single-supply systems. The Enhanced C-Drive TM of NJU77572 can directly drive a 1000pF capacitive load, this feature is ideal for high-speed signal cable drivers and high-speed active filter circuits that are sensitive to wiring capacitance. NJU77572 includes integrated EMI filter to reduce malfunctions caused by RF noises from mobile phones and other wireless devices. NJU77572 operates from supply range of 2.7V to 5.5V over the -55°C to 125°C extended industrial temperature range. The NJU77572 is available in 8-pin SOP8, MSOP (VSP): meet JEDEC MO-187-DA type package.
