Asahi Kasei Microdevices AK4426

The AK4426 is a 5V 24-bit stereo DAC with an integrated 2Vrms output buffer. The AK4426 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 DVD, AV receiver system and set-top boxes.

GENERAL DESCRIPTION

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 AK4426 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4426 is offered in a space saving 16pin TSSOP package.
