Description

  The LMV921 Single/LMV922 Dual/LMV924 Quad are guar-anteed to operate from +1.8V to +5.0V supply voltages and have rail-to-rail input and output. This rail-to-rail operation enablestheusertomakefulluseoftheentiresupplyvoltage range. The input common mode voltage range extends 300mV beyond the supplies and the output can swing rail-to-rail unloaded and within 100mV from the rail with 600 load at 1.8V supply. The LMV921/LMV922/LMV924 areoptimizedtoworkat1.8Vwhichmakethemidealforpor-table two-cell battery-powered systems and single cell Li-Ion systems.

  The LMV921/LMV922/LMV924 exhibit excellent speed-power ratio, achieving 1MHz gain bandwidth product at 1.8V supply voltage with very low supply current. The LMV921/LMV922/LMV924 are capable of driving 600 load and up to 1000pF capacitive load with minimal ringing. The LMV921/LMV922/LMV924's high DC gain of 100dB makes hem suitable for low frequency applications.

  The LMV921 (Single) is offered in a space saving SC705 and SOT235 packages. The SC705 package is only 2.0X2.1X1.0mm. These small packages are ideal solutions for area constrained PC boards and portable electronics such as cellphones and PDAs.
