Features

  • Pre-trimmed VCA & RMS detector
  • Wide supply voltage range: 4.5V to 16V
  • Low supply current: 1.6 mA typ. (5V)
  • Wide dynamic range: 118 dB as compander

The THAT4315 is a single-chip Analog Engine® optimized for low-voltage, low-power operation.

Incorporating a high-performance voltage- controlled amplifier (VCA), RMS-level sensor, the surface mount part is aimed at battery-operated audio applications such as wireless microphones, wireless instruments and in-ear monitors. The 4315 operates from a single supply voltage down to +4.5 Vdc, drawing only 1.6 mA.

This IC also works at supply voltages up to 16 Vdc, making it useful in line-operated products as well. The VCA is pre-trimmed at wafer stage to deliver low distortion without further adjustment.

The part was developed specifically for use as a companding noise reduction system, drawing from THAT's long history and experience with dbx® technology for noise reduction. However, with 11 active pins, the part is extremely flexible and can be configured for a wide range of applications including single and multi-band companders, compressors, limiters, AGCs, de-essers, etc.
