LMV981MGX/NOPB

The LMV98x-N is a low-voltage, low-power op amp operating from 1.8V to 5V supply voltage with rail-to-rail input and output. The input common-mode voltage extends 200mV beyond the supply rails, providing enhanced functionality beyond the supply voltage range. The output swing is rail-to-rail under no load; at a 1.8V supply with a 600Ω load, the output voltage swings to within 105mV of the supply rails. The LMV98x-N is optimized for 1.8V operation, making it ideal for portable dual-cell battery-powered systems and single-cell Li-ion battery systems. The LMV98x-N features a shutdown pin that can be used to disable the device and reduce supply current. When the SHDN pin is driven low, the device enters shutdown mode. In shutdown mode, the output is in a high-impedance state. The LMV98x-N offers an excellent speed-to-power ratio, achieving a 1.4 MHz gain-bandwidth product at low supply current from a 1.8V supply. It can drive 600Ω loads and capacitive loads up to 1000pF with minimal ringing. The LMV98x-N also features a high DC gain of 101dB, making it suitable for low-frequency applications.
