THAT626x Family increases integration and lowers power for low-noise
digitally controlled microphone preamplifiers
Milford, Mass.. – THAT Corporation today announced three new programmable preamplifiers with integrated ADC drivers. The family includes three products with different gain-step sizes: the 6261, 6263, and 6266 at 1dB, 3dB, and 6dB per step, respectively.
“The 626x is the first integrated microphone preamplifier to fully bridge the gap from XLR to ADC. It’s the whole front-end on a chip.” said Ken Nevard, THAT’s IC Marketing Manager. “And, it uses 10 times less power than alternative solutions.”
Key features include:
- Low noise: -127dBu Ein (max gain)
- Wide Gain Range: -8 dB to +34 dB
- Very Low Power 30 mW per channel
- Integrated ADC driver
- Unipolar +10V or Bipolar +/-5V power supplies
- Daisy Chainable SPI Interface
- Small 7mm x 7mm QFN48 Package
All three parts accept up to +16.5dBu input signals, and directly drive common 5 V ADCs to 2 Vrms full-scale. The parts offer very low noise and click-less gain switching, along with on-board zero-crossing detectors (ZCDs). Two general-purpose outputs (GPOs) per channel may be synchronized with that channel’s ZCD.
“With such low power consumption, the 626x is ideal for battery and Power-over-Ethernet (POE) applications.”, said Nevard. “It enables professional audio applications for The Internet of Things (IoT).”
“The 626x family breaks new ground because it’s THAT’s first all-in-one digitally controlled preamp,” added Les Tyler, THAT’s President. “We applied everything we’ve learned from our many separate preamp and controller parts to set a new bar for the category.”
The 626x is available immediately. Pricing starts at $4.56 at 1k pieces (6266). A demonstration board is available to enable quick evaluation.
