Preamp chipset offers high performance
Published time: 2019-12-18 00:00:20
The THAT1570/5171 paired chipset comprises a low-noise differential audio preamplifier (1570) and a separate high-performance digital preamplifier controller (5171). Compared to competing single-chip implementations that operate from only ±5-V supplies, the chipset offers up to 130 dB dynamic range when operating from ±17-V supplies.
The part-pair enables gain to be programmed over 56 1-dB steps from 13.6 to 68.6 dB. An additional gain setting of 5.6 dB allows the combination to accept line inputs up to 22 dBu. Other features include a low noise of 1.5 nV/√Hz at 68.6-dB gain, and 20 nV/√Hz at 5.6-dB gain, a THD+N of 0.0003% at 21.6-dB gain, and wide bandwidth of 1.8 MHz at 40.6-dB gain.
