Description：

The TPA6031/6032/6034 is a series of CMOS dual, andquad RRIO operational amplifiers with low offset, lowpower, and stable high-frequency response. The seriesincorporates proprietary and patented design techniquesof the 3PEAK to achieve excellent AC performancewith 1.5-MHz bandwidth, 0.7-V/μs slew rate, and lowdistortion while drawing only 100 μA of quiescent currentper amplifier. The TPA6031/6032/6034 series can drivecapacitive loads up to 10 μF to maintain stable outputwithout oscillation.The input common-mode voltage range extends 100mV beyond V– and V+, and the outputs swing rail-torail. The TPA6031/6032/6034 series can be used asplug-in replacements for commercially available op ampsto reduce power and improve input/output range andperformance. The combination of features makes theTPA6031/6032/6034 ideal for motor control, portable audioamplification, sound ports, and other consumer audios.The TPA6031/6032/6034 op amps are very stable and arecapable of driving heavy capacitive loads such as thosefound in LCDs. The ability to swing rail-to-rail at the inputsand outputs enables designers to buffer CMOS DACs,ASICs, or other wide-output swing devices in single-supplysystems.
