Description

The AK4430ET 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 AK4430ET delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4430ET 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 AK4430ET is offered in a space saving 16-pin TSSOP package.

Applications

  •                                 Ideal for systems such as Set-Top-Box, portable AV players, and digital TV.
