THAT5171N32-U3CS Digital Preamplifier Controller
Product Code:
THAT5171N32-U3CS
- Wide gain range (63dB)
- 1dB step size from +8dB to +63dB
- Plus 0dB setting
- Handles full pro audio levels
- +22dBu max input with ±17V supplies
- +27dBu max output with ±17V supplies
- Integrated servo and zero crossing detectors minimize dc offsets and zipper noise
The 5171 is a low distortion switched resistor ladder that has been designed to work with the 1570, resulting in a versatile very high performance microphone preamplifier. It will also work equally well with other discrete front end solutions offering designers great opportunities for new products.
The gain is adjustable to 5.6dB, and from 13.6dB to 68.6dB in 1 dB steps with built-in zero crossing detector and other patent-pending techniques for reducing zipper noise, resulting in very smooth and silent gain changes.
Four general purpose outputs on the 5171 can be connected to a variety of peripheral functions, e.g. input pad, phantom power switches, signal routing switches, LED indicators etc.
The addressable SPI interface supports read-back, enabling fault tolerant control software to verify proper operation.
The THAT5171 is fabricated in a high-voltage CMOS process, with proprietary techniques for reducing FET switching glitches. Packaged in 7x7mm QFN32 the THAT5171 takes up very little board space.
There has never been a satisfactory integrated mic pre with digital control until now. With the THAT 1570/5171, designers can now incorporate a preamp with high sonic performance and digital controllability into a wider range of products than ever before.
