1580N16-U

1580N16-U is a versatile, high-performance current-feedback amplifier suitable for differential microphone preamp and bus summing applications. This device's differential output simplifies connection to differential input devices such as A/D converters. The part operates from as little as ±5V up through ±18V supplies. It is designed to mate perfectly with THAT's series of digital preamplifier controller ICs. Designed from the ground up in a high-voltage BiCMOS process, this device improves on existing integrated microphone preamps by offering more versatile gain configuration, lower noise at low gains, higher slew rate, and lower distortion. It is used in applications such as microphone Preamplifiers, digitally-controlled microphone preamplifiers, differential low-noise preamplifiers, differential summing amplifiers, differential variable-gain amplifiers, moving-coil transducer amplifiers, line input stages, audio, sonar, instrumentation.
