THAT4305Q16-U 'Analog Engine' Dynamics Processor

Sku:

THAT4305Q16-U

- +
Features
  • Pre-trimmed VCA and RMS-level detector
  • Wide supply voltage range: ±4.5V to ±16V
  • Low supply current: 3.5 mA typ. (±15V)
  • Wide dynamic range: 117 dB (VCA),60 dB (RMS-level detector)

The THAT4305 is a single-chip Analog Engine optimized for low-cost applications.

It incorporates a high-performance Blackmer® voltage-controlled amplifier (VCA) and log-responding RMS-level sensor. The VCA and RMS detector are pre-trimmed at wafer stage to deliver low distortion without further adjustment.

Available only in a small (QSOP) surface- mount package, the 4305 is aimed at line-operated audio applications such as compressor/limiters, gates, and other dynamic processors. The part normally operates from a split supply voltage up to +16 Vdc, drawing only 3.5 mA at +15 V. This IC also works at supply voltages as low as +4.5 V, making it useful in some battery-operated products as well.

The 4305 was developed specifically for use in low-cost dynamics processors. Both VCA control ports and the detector input and output are available for user configured connection. As a result, the part is extremely flexible and can be configured for a wide range of applications including single- and multi-band companders, digital overload protectors, voltage-controlled faders, level indicators, etc.

What really sets the 4305 apart from other manufacturers' offerings is the transparent sound of its Blackmer VCA, coupled with its accurate true-RMS level detector. This makes the IC useful in a wide range of analog audio products

Demonstration Board THAT4305DEMO is available for this product.
