TLV320AIC3110IRHBT 개요
An audio codec is a device that encodes and decodes digital audio data, converting between analog and digital domains. It typically includes ADCs and DACs, along with signal processing and amplification stages. In a system hierarchy, an audio codec sits between the digital audio processor (e.g., DSP or SoC) and the analog audio output (speakers, headphones) or input (microphones). It is a critical component in portable electronics, automotive infotainment, and IoT devices.
Key features of the TLV320AIC3110 include a 1.3W stereo Class-D speaker amplifier, which provides high efficiency for battery-powered devices. The device supports a wide analog supply range of 2.7V to 3.6V, a digital core supply of 1.525V to 1.95V, and a digital I/O supply of 1.1V to 3.6V. It also includes a programmable digital sine-wave generator and extensive register-based power control for optimizing power consumption.
Technically, the TLV320AIC3110 integrates a low-power stereo DAC with 32-bit resolution and a mono ADC, supporting sample rates up to 96 kHz. The Class-D amplifier delivers 1.3W per channel into 8 ohms with low distortion. The device features a 5x5 mm VQFN package with exposed thermal pad for improved heat dissipation. It operates over the industrial temperature range of -40°C to +85°C.
Typical applications include portable audio players, smartphones, tablets, and IoT devices requiring high-quality audio playback and recording. The integrated Class-D amplifier eliminates the need for an external amplifier, reducing BOM cost and board space. The I2C control interface allows easy integration with microcontrollers and DSPs.
When designing with this device, ensure proper decoupling of the analog and digital supplies, and place the Class-D amplifier output filters close to the device to minimize EMI. The thermal pad should be soldered to a copper pour for effective heat dissipation.

설계 노트
Ensure proper decoupling of AVDD, DVDD, and IOVDD supplies. Place 0.1uF and 10uF capacitors close to each supply pin. The analog and digital supplies should be separated to minimize noise coupling. Use a low-noise LDO for AVDD to achieve optimal audio performance.
For the Class-D amplifier, place LC filters (e.g., 10uH inductor and 1uF capacitor) close to the SPKP and SPKM pins to reduce EMI and ensure stable operation. The exposed pad (EP) should be soldered to a large copper pour for thermal dissipation and connected to ground.
Avoid routing digital signals (I2C, MCLK) near analog audio traces to prevent crosstalk. Ensure the I2C address is correctly configured to avoid conflicts. The Class-D amplifier output should not be left floating; always connect a load or filter.
