Additional Infomation About Product

IS31AP4912 STEREO HEADPHONE DRIVER August 2018 GENERAL DESCRIPTION FEATURES The IS31AP4912 is a Class-AB stereo headphone Supply voltage from 2.7V ~ 5.5V inverting amplifier with charge pump controller capable Ultra-low current shutdown mode of delivering 30mW into a 32 load with less than Ground referenced outputs 0.1% THD+N. The integrated charge pump generates - No output DC-blocking capacitors a negative reference voltage to bias the outputs about Low output noise (7V) ground. This eliminates the need for output DC- High SNR (103dB) blocking capacitors resulting in a lower component count and cost. The gain of the amplifier is adjusted -95dB PSRR via external resistors. Thermal protect circuit Integrated click-and-pop suppression circuitry The IS31AP4912 integrates click-and-pop UTQFN-12 (2mm 2mm) package suppression circuitry to eliminate speaker noise which would occur during power ON/OFF transitions. It also integrates a thermal protection circuit to shutdown the APPLICATIONS amplifier if it gets too hot. Setting the SDB pin to a low state will cause the IS31AP4991 to enter a low-power Cellular handsets and PDAs shutdown mode with a quiescent current of less than Notebook PC 1A. MP3 The IS31AP4912 is ideal for small portable electronics Portable gaming where size, battery life and cost are critical design parameters. IS31AP4912 is available in a space saving UTQFN-12 (2mm 2mm) package. It operates from 2.7V to 5.5V over the temperature range of -40C to +85C. TYPICAL APPLICATION CIRCUIT Figure 1 Typical Application Circuit Note 1: The SGND and PGND pins of the IS31AP4912 must be routed separately back to the decoupling capacitor in order to provide optimum device operation. If the SGND and PGND pins are connected directly to each other, the device will function, but the noise and THD performance do not meet the specifications.
