LMV932M/TR

LMV932 1 MHz Bandwidth Low Power Op Amp Features Description • • • • • • 1 MHz Gain Bandwidth Product (typ.) Rail-to-Rail Input/Output Supply Voltage: 1.8V to 5.5V Supply Current: IQ = 100 µA (typ.) 90° Phase Margin (typ.) Temperature Range: - Industrial: -40°C to +85°C - Extended: -40°C to +125°C • Available in Single, Dual and Quad Packages LMV932 operational amplifiers (op amps) is specifically designed for general-purpose applications. This family has a 1 MHz gain bandwidth product and 90° phase margin (typ.). It also maintains 45° phase margin (typ.) with 500 pF capacitive load. This family operates from a single supply voltage as low as 1.8V, while drawing 100 µA (typ.) quiescent current. Additionally, the LM932 supports rail-to-rail input and output swing with a common mode input voltage range of VDD + 300 mV to V SS - 300 mV. This family of operational amplifiers is designed with Microchip’s advanced CMOS process. Applications The LMV932 family is available in the industrial and extended temperature ranges. It also has a power supply range of 1.8V to 5.5V. • • • • • • Automotive Portable Equipment Photodiode Pre-amps Analog Filters Notebooks and PDAs Battery-Powered Systems Package Types LMV932 Typical Application PDIP, SOIC, MSOP VDD VIN VOUTA 1 VINA– 2 + VINA+ 3 VOUT LMV932 - VSS 4 8 VDD A - + 7 VOUTB B + - 6 V 5 V VSS R1 R2 VREF R1 Gain = 1 + -----R2 Non-Inverting Amplifier 1 2016 APR LMV932 1.0 ELECTRICAL CHARACTERISTICS PIN FUNCTION TABLE Name Absolute Maximum Ratings † VDD - VSS .........................................................................7.0V All Inputs and Outputs ......................
