Product details
Overview
TLV320AIC23BIPWRQ1 from Texas Instruments is an AEC-Q100 qualified stereo audio codec with integrated headphone amplifier, 90-dB SNR ADC and 100-dB SNR DAC, supporting 8–96 kHz sampling rates and delivering 30 mW per channel into 32 Ω. It serves as the analog I/O interface in automotive infotainment head units and portable digital audio recorders.
For engineers reviewing the TLV320AIC23BIPWRQ1 datasheet, TLV320AIC23BIPWRQ1 pinout, TLV320AIC23BIPWRQ1 application, or TLV320AIC23BIPWRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, I²S/McBSP-compatible digital interface, programmable microphone gain (0 dB/20 dB), analog bypass path, and 23-mW playback power consumption.
Technical Context
The TLV320AIC23BIPWRQ1 implements third-order multibit sigma-delta ADC architecture achieving up to 90-dBA SNR and second-order multibit sigma-delta DAC architecture achieving up to 100-dBA SNR - both at 48 kHz with A-weighting. It supports 16/20/24/32-bit word lengths and master/slave timing modes with industry-standard (256/384 fs) and TI-optimized (250/272 fs) oversampling rates.
Dual independent volume control paths provide 1.5-dB-step gain adjustment (–34.5 dB to +12 dB) for line inputs and 1-dB-step gain (–73 dB to +6 dB) for headphone outputs, while integrated electret microphone bias (MICBIAS = 3/4 AVDD) and programmable microphone amplifier enable direct capsule interfacing without external components.

FAQ
What is the AEC-Q100 qualification grade for TLV320AIC23BIPWRQ1?
The TLV320AIC23BIPWRQ1 is qualified to AEC-Q100 Grade 2, specifying operation from –40°C to +85°C ambient temperature. This qualification confirms reliability under automotive thermal stress conditions, including temperature cycling and humidity exposure. The device meets all stress tests defined in the AEC-Q100 standard for packaged ICs, and its datasheet explicitly states "Qualified for Automotive Applications." TLV320AIC23BIPWRQ1 is therefore suitable for use in instrument clusters, center consoles, and other non-engine-compartment automotive electronics.
Does TLV320AIC23BIPWRQ1 support I²S interface without additional level-shifting?
Yes, TLV320AIC23BIPWRQ1 supports native I²S communication using its DIN, DOUT, BCLK, and LRCIN/LRCOUT pins - no level-shifting is required when interfacing with TI C54x DSPs or other 3.3-V logic devices. Its digital I/O thresholds are defined relative to BVDD (2.7–3.6 V), and VIH/VIL specifications (0.7×BVDD / 0.3×BVDD) ensure robust compatibility. The device also supports MSB-justified and LSB-justified formats, and operates in both master and slave timing modes. TLV320AIC23BIPWRQ1 achieves glueless connection to TI McBSP peripherals by matching signal timing and voltage levels directly.
Can TLV320AIC23BIPWRQ1 drive headphones directly without external amplification?
Yes, TLV320AIC23BIPWRQ1 integrates a highly efficient linear headphone amplifier capable of delivering 30 mW per channel into 32 Ω loads at 3.3 V supply, with programmable gain from –73 dB to +6 dB in 1-dB steps. This eliminates the need for external headphone drivers in space-constrained applications like portable recorders or automotive rear-seat entertainment. The LHPOUT and RHPOUT pins provide fully buffered, DC-coupled outputs requiring only series AC-coupling capacitors. TLV320AIC23BIPWRQ1 maintains 88–97 dB A-weighted SNR at 10–20 mW output, ensuring clean audio reproduction.
What microphone interface options does TLV320AIC23BIPWRQ1 provide?
TLV320AIC23BIPWRQ1 provides a complete electret microphone interface: MICBIAS supplies a low-noise 3/4 AVDD bias voltage, MICIN accepts the capsule signal with default 5× gain, and two programmable gain stages are available - a fixed 0 dB or 20 dB boost, plus adjustable 1×–5× gain. The microphone path supports sidetone mixing into headphone outputs for real-time monitoring. Input resistance (8–14 kΩ) and capacitance (≤10 pF) are optimized for common electret capsules. TLV320AIC23BIPWRQ1 thus enables direct, high-SNR microphone connection without external op-amps or bias networks.
How does TLV320AIC23BIPWRQ1 handle clocking for TI C54x DSPs?
TLV320AIC23BIPWRQ1 supports TI-optimized oversampling rates of 250 fs and 272 fs - specifically engineered to align with C54x DSP serial port timing. When driven by a 12-MHz crystal on XTI/MCLK, the internal oscillator generates exact multiples needed for 44.1 kHz and 48 kHz audio sampling without fractional dividers. CLKOUT can output 12 MHz or 6 MHz to synchronize the DSP and other peripherals. This eliminates clock domain mismatches and jitter introduced by external PLLs. TLV320AIC23BIPWRQ1 thus enables deterministic, low-jitter audio data transfer between the codec and TI C54x processors in automotive and industrial systems.
