This document introduces the TLV320DAC3120, a low-power, highly integrated, high-performance mono DAC that supports 8-kHz to 192-kHz sample rates and has a built-in mono speaker driver capable of driving a 4-Ω load.
The TLV320DAC3120 is a highly integrated mono audio DAC that includes a programmable miniDSP, microphone bias, headphone/line‑out driver, and a Class‑D BTL speaker driver capable of driving a 4‑Ω load. It supports sample rates from 8 kHz to 192 kHz and offers digital audio processing such as programmable biquad, FIR filters, and bass‑boost/EQ.
The device is supplied in a 5 mm × 5 mm 32‑pin QFN package and operates from analog supplies of 2.7 V‑3.6 V, digital core supplies of 1.65 V‑1.95 V, and a Class‑D supply of 2.7 V‑5.5 V. Typical applications include portable audio devices and navigation units.
