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-torail.

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.
