THAT 4316Q16-U

The THAT4316 is a single-chip Analog Engine optimized for very low-voltage, low-power operation. It incorporates a high-performance class-AB voltage-controlled amplifier (VCA) and true-RMS-responding level detector. The 16-pin QSOP part is aimed at battery-operated audio applications including companding systems for wireless microphones, wireless instruments, and in-ear monitors, as well as dynamics processors of all types. The 4316 operates from a single supply voltage down to 2.7V, drawing only 1.2mA at 3.3V
