HGSEMI LMV721AM5/TR

The LMV72xA features an 11MHz gain bandwidth product, 9V/μs slew rate, and 1.1mA quiescent current per amplifier at 5V. The LMV72xA is designed to provide optimal performance in low-voltage, low-noise systems. They deliver rail-to-rail output swing for heavy loads. The input common-mode voltage range includes ground, and the LMV72xA has a maximum input offset voltage of 3.5mV. They are specified over the extended industrial temperature range (-40°C to +125°C). The operating range is 2.1V to 5.5V. The single-channel LMV721A is available in green SC70-5, SOT23-5, SOP-8, and MSOP-8 packages. The dual-channel LMV722A is available in green SOP-8 and MSOP-8 packages. The quad-channel LMV724A is available in green SOP-14 and TSSOP-14 packages. The LMV72xA series op amps are unity-gain stable and suited for a wide range of general-purpose applications. The small package sizes of the LMV72xA series save PCB space and enable smaller electronic product designs. The LMV72xA series can be powered by a single supply from 2.1V to 5.5V or a dual supply of ±1.05V to ±2.75V. For best performance, a 0.1µF ceramic capacitor should be placed near the VDD pin during single-supply operation. For dual-supply operation, both the VDD and VSS supplies should be bypassed to ground with separate 0.1µF ceramic capacitors. The low supply current of the LMV72xA series (typical 1.1mA per channel) helps maximize battery life. They are ideal for battery-powered systems. The LMV72xA series operates over a wide supply voltage range (2.1V to 5.5V). Furthermore, all temperature specifications apply from -40°C to +125°C. Most characteristics remain constant over the entire operating voltage range. These guarantees ensure proper operation throughout the full service life of a single lithium-ion battery. The input common-mode range of the LMV72xA series extends 100mV beyond the supply rails (VSS - 0.1V to VDD + 0.1V), achieved through the use of a complementary input stage. During normal operation, inputs should be kept within this range. Rail-to-rail output swing provides the maximum possible dynamic range at the output, which is especially important when operating at low supply voltages. The output voltage of the LMV72xA series typically swings to within 2mV of either supply rail under light resistive loads (>100kΩ), and to within 15mV of either supply rail under moderate resistive loads (10kΩ). The LMV72xA series is optimized for bandwidth and speed rather than for driving capacitive loads. Output capacitance introduces a pole in the amplifier's feedback path, causing excessive peaking and potential oscillation. If the application requires handling load capacitance, two strategies may be considered: (1) place a small series resistor between the amplifier output and the load capacitance; (2) reduce the bandwidth of the amplifier feedback loop by increasing the overall noise gain.
