AEC-Q100 qualified for automotive applications

– Temperature grade 1: –40°C ≤ T_A≤ +125°C

3 Description

•

ADC Channel

– Performance:

The TAC5412-Q1 is a high performance Stereo

Codec with 10V_RMSdifferential Input, 108dB Stereo

ADC and 2V_RMSStereo DAC Channels. The

TAC5412-Q1 supports both differential and Single

Ended input and output. Device supports both

Microphone and Line In input on ADC Channel.

DAC Output can be configured for either Line Out

or Head Phone Load. TAC5412-Q1 can drive up

to 62.5mW into a Headphone Load. The device

also offers an integrated high-voltage, programmable

microphone bias, and input diagnostic circuitry

that allows direct connection to microphone-based

automotive systems with full fault diagnostic capability

for direct-coupled inputs. The TAC5412-Q1 integrates

an efficient boost converter to generate a high voltage

microphone bias using an external, low-voltage,

3.3V supply, The device can also directly use an

external high-voltage supply (HVDD), which is a

readily available supply in the system to generate

the high-voltage, programmable microphone bias.

The TAC5412-Q1 integrates programable channel

gain, digital volume control, a low-jitter phase-locked

loop (PLL), a programmable high-pass filter (HPF),

programmable EQ and biquad filters, low-latency filter

modes. It allows for sample rates up to 768kHz.

The TAC5412-Q1 supports time-division multiplexing

(TDM), I²S, or left-justified (LJ) audio formats, and

can be controlled with I²C. These integrated high-

performance features, along with a single, 3.3V

supply operation, makes TAC5412-Q1 an excellent

choice for space-constrained automotive systems.
