THAT 4320Q28-U

The THAT 4320 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 opamps, 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 +4.5Vdc, drawing only 3.7mA.
