LMV931

LMV931 Single / LMV932 Dual / LMV934 Quad 1.8V, RRIO Operational Amplifiers December 2002 LMV931 Single / LMV932 Dual / LMV934 Quad 1.8V, RRIO Operational Amplifiers General Description The LMV931/LMV932/LMV934 are low voltage, low power operational amplifiers. LMV931/LMV932/LMV934 are guaranteed to operate from +1.8V to +5.0V supply voltages and have rail-to-rail input and output. LMV931/LMV932/LMV934 input common mode voltage extends 200mV beyond the supplies which enables user enhanced functionality beyond the supply voltage range. The output can swing rail-to-rail unloaded and within 105mV from the rail with 600Ω load at 1.8V supply. The LMV931/LMV932/LMV934 are optimized to work at 1.8V which make them ideal for portable two-cell battery powered systems and single cell Li-Ion systems. LMV931/LMV932/LMV934 exhibit excellent speed-power ratio, achieving 1.4MHz gain bandwidth product at 1.8V supply voltage with very low supply current. The LMV931/LMV932/ LMV934 are capable of driving a 600Ω load and up to 1000pF capacitive load with minimal ringing. LMV931/ LMV932/LMV934 have a high DC gain of 101dB, making them suitable for low frequency applications. The single LMV931 is offered in space saving SC70-5 and SOT23-5 packages. The dual LMV932 are in MSOP-8 and SOIC-8 packages and the quad LMV934 are in TSSOP-14 and SOIC-14 packages. These small packages are ideal solutions for area constrained PC boards and portable electronics such as cellular phones and PDAs. Features (T...
