High-Performance, Fully Differential <strong>Audio</strong> Op Amp<br />
OPA1632<br />

Gain, attenuation and filtering are fundamental in all audio processing.<br />
TI has a long history in op amps, instrumentation amplifiers and line<br />
drivers/receivers, ranging from the OPA627 through to the ultra-lownoise<br />
OPA1632. TI's range of line drivers and receivers are among the<br />
workhorses of the audio industry, driving signals from system to system<br />
in home, studio and broadcast applications.<br />
TI recently released the OPA1632, a fully differential operational amplifier<br />
aimed at gain-scaling and interfacing to high-performance ADCs.<br />
The OPA1632’s low THD+N and ±16-V supply rail make it an ideal signal<br />
chain op amp for maintaining true balance throughout your system.<br />

Key Features<br />
• True balanced architecture: balanced input and output converts single-ended<br />
input to balanced differential output.<br />
• GBW of 180 MHz and very fast slew rate of 50 V/µs produce exceptionally<br />
low distortion.<br />
• Very low input noise of 1.3 nV√Hz ensures maximum signal-to-noise<br />
ratio and dynamic range.<br />
Applications<br />
• <strong>Audio</strong> ADC drivers<br />
• Balanced line drivers<br />
• Balanced receivers<br />
To Know More<br />
