Frequently Asked Questions

How many ADC and DAC channels does TLV320AIC23BRHDG4 provide, and to what bit depth?

The codec integrates 2 ADC channels for stereo recording and 2 DAC channels for stereo playback, both supporting up to 32-bit word length. Sample rates are programmable from 8 kHz for voice telephony to 96 kHz for high-fidelity audio applications, covering the full consumer and professional audio range.

Which audio serial interfaces does TLV320AIC23BRHDG4 support for connecting to a microcontroller or DSP?

TLV320AIC23BRHDG4 supports I2S, DSP mode, left-justified, and right-justified audio serial formats, making it compatible with most microcontroller I2S peripherals and DSP serial ports without adaptation circuitry. Register configuration is handled over a separate I2C or SPI control bus, allowing the audio data path and control path to operate independently at 1.42 V to 3.6 V supply.

For a battery-powered handheld audio device, how does the supply voltage requirement of TLV320AIC23BRHDG4 benefit the design?

The analog supply accepts 1.42 V to 3.6 V, allowing direct operation from a single Li-ion cell at 3.0 V or a regulated 1.8 V rail, reducing the need for boost regulators in portable designs. Combined with the 32-bit DAC and headphone driver on-chip, this integration minimizes the component count in space-constrained 3.3 V handheld audio products.

What package does TLV320AIC23BRHDG4 come in, and how many pins does it have?

The device is housed in a 28-pin VQFN (Very thin Quad Flat No-Lead) package with an exposed thermal pad on the underside, measuring approximately 5 mm x 5 mm. The QFN format enables a compact PCB footprint with short signal traces and better thermal dissipation compared to 28-pin SOIC alternatives in audio module designs.

Which application scenario benefits most from TLV320AIC23BRHDG4 versus using separate ADC and DAC chips?

Designs requiring simultaneous full-duplex stereo capture and playback, such as a VoIP handset or digital dictation recorder, benefit most from TLV320AIC23BRHDG4's integrated approach. A single 28-pin chip replaces a standalone 16-bit ADC, a separate 16-bit DAC, headphone amplifier, and microphone bias circuit, reducing BOM cost and PCB area while sharing a common 8 kHz to 96 kHz clock source.
