The integrated phantom ground is a circuit topology that eliminates the heavy output coupling capacitors. This is of primary importance in portable applications where space constraints are very high. A single-ended configuration is also available, offering even lower power consumption because the phantom ground can be switched off. Pop-and-click noise during switch-on and switchoff phases is eliminated by integrated circuitry. January 2013 This is information on a product in full production. Specially designed for applications requiring low power supplies, the TS4909 is capable of delivering 31 mW of continuous average power into a 32 Ω load with less than 1% THD+N from a 3 V power supply. Featuring an active low standby mode, the TS4909 reduces the supply current to only 10 nA (typ.). The TS4909 is unity gain stable and can be configured by external gain-setting resistors.
