Full description
The THAT1570 is an ultra high-performance versatile audio preamplifier suitable for microphone preamp, bus summing and industrial measurement applications. It has been designed to work with THAT's range of digital controllers with gain setting in 1dB or 3dB steps.
Operating on maximum of ±18V supplies the preamplifier accepts pro-audio levels (+28dBu) without an input pad. Combine this with just 1nV/√Hz noise at 60dB gain and you have a truely high performance pre-amplifier. Even greater flexibility is possible using your own custom controller circuits made possible by the topolgy of the 1570.
The analogue THAT1570 is fabricated using THAT's complementary dielectric isolation (DI) process and precision laser-trimmed Si-Chrome thin film resistors. DI technology separates each transistor in its own insulating tub, avoiding the inevitable crosstalk of conventional reverse-biased junction isolating techniques but retaining the transistor matching and temperature tracking inherent in integrated circuits. The result is a preamp with the sound of a discrete and the performance and stability of an IC.
