What the BA4580RF family does
The BA4580Rxxx, BA4584FV, and BA4584Rxx are low noise operational amplifiers integrating two or four independent high voltage gain stages on a single chip. These devices feature a wide operating supply voltage range from ±2V to ±16V, delivering 5V/µs slew rate and 5nV/√Hz input referred noise. They maintain low distortion at 0.0005% typical and support operating temperatures from -40°C to +105°C. Engineers typically select these amplifiers for audio applications due to their superior noise and distortion characteristics, while also utilizing them in consumer electronics and other systems requiring wide voltage tolerance. Available in multiple packages including SOP8, TSSOP-B8, and SSOP-B14, the series offers flexibility for various industrial and commercial designs.
