- +
Features
  • Pre-trimmed VCA & RMS detector
  • Wide supply voltage range: 4.5V~16V
  • Low supply current: 3.7mA typ. (5V)
  • Four op-amps
  • One low-noise op-amp (<5nV/√Hz)
  • On board PTAT reference
  • Wide dynamic range: 120dB as compander

The THAT4320 is a single-chip Analog Engine® optimized for low-voltage, low-power operation.

Incorporating a high-performance voltage- controlled amplifier (VCA), RMS-level sensor, and four op-amps, the surface mount part is aimed at battery-operated audio applications such as wireless microphones, wireless instruments and in-ear monitors.

The 4320 operates from a single supply voltage down to +4.5 Vdc, drawing only 3.7 mA.

The VCA is pre-trimmed at wafer stage to deliver low distortion without further adjustment.

One op-amp is quiet enough to be used as a microphone preamp.

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 22 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.

Demonstration Board THAT4320DEMO is available for this product.
