The TBA 231 A is a monolithic integrated dual operational amplifier in a 14-lead dual in-line plastic
package.
These low-noise, high-gain amplifiers show extremely stable operating characteristics over a wide range
of supply voltage and temperatures.
The device is intended for a variety of applications requiring two high performance operational ampli-
fiers, such as phono and tape stereo preamplifier, TV remote control receiver, etc.
