Description

The NJU77580/NJU77582 are single and dual rail-to-rail input and output single supply OpAmp featuring wide bandwidth and low noise. The combination of very low noise (6nV√Hz at 10kHz), high-gain bandwidth (20MHz), and fast slew rate (10V/µs) make the devices ideal for a wide variety of applications, including signal conditioning and sensor amplification requiring high gains. 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 of NJU77580/NJU77582 can directly drive a 1000pF capacitive load, and can output an AC signal with little distortion even with a large capacitive load by suppressing the decrease in GBW. This feature is ideal for high-speed signal cable drivers and high-speed active filter circuits that are sensitive to wiring capacitance. NJU77580/NJU77582 includes integrated EMI filter to reduce malfunctions caused by RF noises from mobile phones and other wireless devices. And the input tolerant that allows the input voltage (Recommended: V− + 5.5V) that exceed positive supply voltage is ideal for design for robust industrial applications. NJU77580/NJU77582 operates from supply range of 2.7V to 5.5V over the -55°C to 125°C extended industrial temperature range. The NJU77580 is available in 5-pin SOT-23-5 package. The NJU77582 is available in 8-pin SOP8, MSOP (VSP) package, and DFN (ESON) that is thin and 2mm square small package.
