AK4430ETP-E2 electronics ic chips , Integrated circuit Chip 3.0V - 3.6V

GENERAL DESCRIPTION The AK4430 is 3.3V 24-bit stereo DAC with an integrated 2Vrms output buffer. A charge pump in the buffer develops an internal negative power supply rail that enables a ground-referenced 2Vrms output. Using AKM’s multi bit modulator architecture, the AK4430 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4430 integrates a combination of switched-capacitor and continuous-time filters, increasing performance for systems with excessive clock jitter. The 24-bit word length and 192kHz sampling rate make this part ideal for a wide range of consumer audio applications, such as portable A/V players, set-top boxes, and digital televisions. The AK4430 is offered in a space saving 16pin TSSOP package.
