Description

The TPA6031/6032/6034 is a series of CMOS dual, and quad RRIO operational amplifiers with low offset, low power, and stable high-frequency response. The series incorporates 3PEAK’s proprietary and patented design techniques to achieve excellent AC performance with 1.5-MHz bandwidth, 0.7-V/ μs slew rate, and low distortion while drawing only 100 μA of quiescent current per amplifier. The TPA6031/6032/6031 series can drive capacitive loads up to 10uF to maintain stable output without oscillation. The input common-mode voltage range extends 100 mV beyond V– and V+, and the outputs swing rail-to- rail. The TPA6031/6032/6034 series can be used as plug-in replacements for commercially available op amps to reduce power and improve input/output range and performance. The combination of features makes the TPA6031/6032/6034 ideal for motor control, portable audio amplification, sound ports, and other consumer audios. The TPA6031/6032/6034 op amps are very stable and are capable of driving heavy capacitive loads such as those found in LCDs. The ability to swing rail-to-rail at the inputs and outputs enables designers to buffer CMOS DACs, ASICs, or other wide-output swing devices in single-supply systems.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. (2) The inputs and outputs are protected by ESD protection diodes to each power supply. If the input or output extends more than 300 mV beyond the power supply, the current should be limited to less than 10 mA. (3) A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many comparators are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads.
