1 Introduction
The TLV320AIC23B is a high-performance stereo audio codec with highly integrated analog functionality. The
analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) within the TLV320AIC23B use multibit
sigma-delta technology with integrated oversampling digital interpolation filters. Data-transfer word lengths of 16, 20,
24, and 32 bits, with sample rates from 8 kHz to 96 kHz, are supported. The ADC sigma-delta modulator features
third-order multibit architecture with up to 90-dBA signal-to-noise ratio (SNR) at audio sampling rates up to 96 kHz,
enabling high-fidelity audio recording in a compact, power-saving design. The DAC sigma-delta modulator features
a second-order multibit architecture with up to 100-dBA SNR at audio sampling rates up to 96 kHz, enabling
high-quality digital audio-playback capability, while consuming less than 23 mW during playback only. The
TLV320AIC23B is the ideal analog input/output (I/O) choice for portable digital audio-player and recorder
applications, such as MP3 digital audio players.
Integrated analog features consist of stereo-line inputs with an analog bypass path, a stereo headphone amplifier,
with analog volume control and mute, and a complete electret-microphone-capsule biasing and buffering solution.
The headphone amplifier is capable of delivering 30 mW per channel into 32 Ω. The analog bypass path allows use
of the stereo-line inputs and the headphone amplifier with analog volume control, while completely bypassing the
codec, thus enabling further design flexibility, such as integrated FM tuners. A microphone bias-voltage output
provides a low-noise current source for electret-capsule biasing. The AIC23B has an integrated adjustable
microphone amplifier (gain adjustable from 1 to 5) and a programmable gain microphone amplifier (0 dB or 20 dB).
The microphone signal can be mixed with the output signals if a sidetone is required.
While the TLV320AIC23B supports the industry-standard oversampling rates of 256 fs and 384 fs, unique
oversampling rates of 250 fs and 272 fs are provided, which optimize interface considerations in designs using TI C54x
digital signal processors (DSPs) and universal serial bus (USB) data interfaces. A single 12-MHz crystal can supply
clocking to the DSP, USB, and codec. The TLV320AIC23B features an internal oscillator that, when connected to a
12-MHz external crystal, provides a system clock to the DSP and other peripherals at either 12 MHz or 6 MHz, using
an internal clock buffer and selectable divider. Audio sample rates of 48 kHz and compact-disc (CD) standard 44.1
kHz are supported directly from a 12-MHz master clock with 250 fs and 272 fs oversampling rates.
Low power consumption and flexible power management allow selective shutdown of codec functions, thus
extending battery life in portable applications. This design solution, coupled with the industry’s smallest package, the
TI proprietary MicroStar Junior using only 25 mm2 of board area, makes powerful portable stereo audio designs
easily realizable in a cost-effective, space-saving total analog I/O solution: the TLV320AIC23B.

3 How to Use the TLV320AIC23B
3.1 Control Interfaces
The TLV320AIC23B has many programmable features. The control interface is used to program the registers of the
device. The control interface complies with SPI (three-wire operation) and two-wire operation specifications. The
state of the MODE terminal selects the control interface type. The MODE pin must be hardwired to the required level.
3.1.1
MODE
INTERFACE
0
2-wire
1
SPI
SPI
In SPI mode, SDIN carries the serial data, SCLK is the serial clock and CS latches the data word into the
TLV320AIC23B. The interface is compatible with microcontrollers and DSPs with an SPI interface.
A control word consists of 16 bits, starting with the MSB. The data bits are latched on the rising edge of SCLK. A rising
edge on CS after the 16th rising clock edge latches the data word into the AIC (see Figure 3-1).
The control word is divided into two parts. The first part is the address block, the second part is the data block:

3.1.2
2-Wire
In 2-wire mode, the data transfer uses SDIN for the serial data and SCLK for the serial clock. The start condition is
a falling edge on SDIN while SCLK is high. The seven bits following the start condition determine which device on
the 2-wire bus receives the data. R/W determines the direction of the data transfer. The TLV320AIC23B is a write only
device and responds only if R/W is 0. The device operates only as a slave device whose address is selected by setting
the state of the CS pin as follows.
CS STATE
(Default = 0)
ADDRESS
0
0011010
1
0011011
3−1
The device that recognizes the address responds by pulling SDIN low during the ninth clock cycle, acknowledging
the data transfer. The control follows in the next two eight-bit blocks. The stop condition after the data transfer is a
rising edge on SDIN when SCLK is high (see Figure 3-2).
The 16-bit control word is divided into two parts. The first part is the address block, the second part is the data block:

3.2 Analog Interface
3.2.1
Line Inputs
The TLV320AIC23B has line inputs for the left and the right audio channels (RLINEIN and LLINEIN). Both line inputs
have independently programmable volume controls and mutes. Active and passive filters for the two channels
prevent high frequencies from folding back into the audio band.
The line-input gain is logarithmically adjustable from 12 dB to –34.5 dB in 1.5-dB steps. The ADC full-scale range
is 1.0 VRMS at AVDD = 3.3 V. The full-scale range tracks linearly with analog supply voltage AVDD. To avoid distortions,
it is important not to exceed the full-scale range.
The gain is independently programmable on both left and right line-inputs. To reduce the number of software write
cycles required. Both channels can be locked to the same value by setting the RLS and LRS bits (see Section 3.1.3).
The line inputs are biased internally to VMID. When the line inputs are muted or the device is set to standby mode,
the line inputs are kept biased to VMID using special antithump circuitry. This reduces audible clicks that otherwise
might be heard when reactivating the inputs.
For interfacing to a CD system, the line input should be scaled to 1 VRMS to avoid clipping, using the circuit shown
in Figure 3-3.

R1 and R2 divide the input signal by two, reducing the 2 VRMS from the CD player to the nominal 1 VRMS of the AIC23B
inputs. C1 filters high-frequency noise, and C2 removes any dc component from the signal.

3.2.2
Microphone Input
MICIN is a high-impedance, low-capacitance input that is compatible with a wide range of microphones. It has a
programmable volume control and a mute function. Active and passive filters prevent high frequencies from folding
back into the audio band.
The MICIN signal path has two gain stages. The first stage has a nominal gain of G1 = 50 k/10 k = 5. By adding an
external resistor (RMIC) in series with MICIN, the gain of the first stage can be adjusted by G1 = 50 k/(10 k + RMIC).
For example, RMIC = 40 k gives a gain of 0 dB. The second stage has a software programmable gain of 0 dB or 20
dB (see Section 3.1.3).

Figure 3−4. Microphone Input Circuit
The microphone input is biased internally to VMID. When the line inputs are muted, the MICIN input is kept biased
to VMID using special antithump circuitry. This reduces audible clicks that may otherwise be heard when reactivating
the input.
The MICBIAS output provides a low-noise reference voltage suitable for biasing electret type microphones and the
associated external resistor biasing network. The maximum source current capability is 3 mA. This limits the smallest
value of external biasing resistors that safely can be used.
The MICBIAS output is not active in standby mode.
3.2.3
Line Outputs
The TLV320AIC23B has two low-impedance line outputs (LLINEOUT and RLINEOUT) capable of driving line loads
with 10-kΩ and 50-pF impedances.
The DAC full-scale output voltage is 1.0 VRMS at AVDD = 3.3 V. The full-scale range tracks linearly with the analog
supply voltage AVDD. The DAC is connected to the line outputs via a low-pass filter that removes out-of-band
components. No further external filtering is required in most applications.
The DAC outputs, line inputs, and the microphone signal are summed into the line outputs. These sources can be
switched off independently. For example, in bypass mode, the line inputs are routed to the line outputs, bypassing
the ADC and the DAC. If sidetone is enabled, the microphone signal is routed to both line outputs via a four-step
programmable attenuation circuit.
The line outputs are muted by either muting the DAC (analog) or soft muting (digital) and disabling the bypass and
sidetone paths (see Section 3.1.3).
3.2.4
Headphone Output
The TLV320AIC23B has stereo headphone outputs (LHPOUT and RHPOUT), and is designed to drive 16-Ω or 32-Ω
headphones. The headphone output includes a high-quality volume control and mute function.
The headphone volume is logarithmically adjustable from 6 dB to –73 dB in 1-dB steps. Writing 000000 to the
volume-control registers (see Section 3.1.3) mutes the headphone output. When the headphone output is muted or
the device is placed in standby mode, the dc voltage is maintained at the outputs to prevent audible clicks.
A zero-cross detection circuit is provided under the control of the LZC and RZC bits. If this circuit is enabled, the
volume-control values are updated only when the input signal to the gain stage is close to the analog ground level.
3−6
This minimizes audible clicks as the volume is changed or the device is muted. This circuit has no time-out, so, if only
dc levels are being applied to the gain stage input of more than 20 mV, the gain is not updated.
The gain is independently programmable on the left and right channels. Both channels can be locked to the same
value by setting the RLS and LRS bits (see Section 3.1.3).
3.2.5
Analog Bypass Mode
The TLV320AIC23B includes a bypass mode in which the analog line inputs are directly routed to the analog line
outputs, bypassing the ADC and DAC. This is enabled by selecting the bypass bit in the analog audio path control
register[see Section 3.1.3).
For a true bypass mode, the output from the DAC and the sidetone should be disabled. The line input and headphone
output volume controls and mutes are still operational in bypass mode. Therefore the line inputs, DAC output, and
microphone input can be summed together. The maximum signal at any point in the bypass path must be no greater
than 1.0Vrms at AVDD=3.3V to avoid clipping and distortion. This amplitude tracks linearly with AVDD.
3.2.6
Sidetone Insertion
The TLV320AIC23B has a sidetone insertion made where the microphone input is routed to the line and headphone
outputs. This is useful for telephony and headset applications. The attenuation of the sidetone signal may be set to
−6 dB, −9 dB, −12 dB, −15 dB, or 0dB, by software selection (see Section 3.1.3). If this mode is used to sum the
microphone input with the DAC output and line inputs, care must be taken not to exceed signal level to avoid clipping
and distortion.
3.3 Digital Audio Interface
3.3.1
Digital Audio-Interface Modes
The TLV320AIC23B supports four audio-interface modes.

•
Right justified
Left justified
I2S mode
DSP mode
The four modes are MSB first and operate with a variable word width between 16 to 32 bits (except right-justified
mode, which does not support 32 bits).
The digital audio interface consists of clock signal BCLK, data signals DIN and DOUT, and synchronization signals
LRCIN and LRCOUT. BCLK is an output in master mode and an input in slave mode.
3.3.1.1 Right-Justified Mode
In right-justified mode, the LSB is available on the rising edge of BCLK, preceding a falling edge on LRCIN or LRCOUT
(see Figure 3-5).

Sync signal of the McBSP. A falling edge on LRCIN or LRCOUT starts the data transfer. The left-channel data consists
of the first data word, which is immediately followed by the right channel data word (see Figure 3-8). Input word length
is defined by the IWL register. Figure 3−8 shows LRP = 1 (default LRP = 0).

Audio Sampling Rates
The TLV320AIC23B can operate in master or slave clock mode. In the master mode, the TLV320AIC23B clock and
sampling rates are derived from a 12-MHz MCLK signal. This 12-MHz clock signal is compatible with the USB
specification. The TLV320AIC23B can be used directly in a USB system.
In the slave mode, an appropriate MCLK or crystal frequency and the sample rate control register settings control
the TLV320AIC23B clock and sampling rates.
The settings in the sample rate control register control the clock mode and sampling rates.

The clock circuit of the AIC23B has two internal dividers. The first, controlled by CLKIN, applies to the sampling-rate
generator of the codec. The second, controlled by CLKOUT, applies only to the CLKOUT terminal. By setting CLKIN
to 1, the entire codec is clocked with half the frequency, effectively dividing the resulting sampling rates by two. The
following sampling-rate tables are based on CLKIN = MCLK.
