3 Description

The TAC5301-Q1 is an automotive, low-power

mono audio codec with 2VRMS differential input,

100dB dynamic range ADC and a DAC with

2VRMS differential output, 110dB dynamic range

mono channel or 1VRMS single-ended output, 107dB

dynamic range stereo channels. The TAC5301-Q1

supports both differential and single-ended inputs

and outputs. The ADC supports both line/microphone

input signals with options for AC or DC coupling

configurations. The DAC outputs can be configured

for either line-output or headphone loads. The DAC

can drive up to 62.5mW into a 16Ω headphone load.

Further, the device has the capability to directly use

an external high-voltage supply (HVDD), which is any

readily available supply in the system to generate

a high-voltage, programmable microphone bias. The

TAC5301-Q1 integrates programmable 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

and ultra low-latency filter modes and supports

sample rates up to 192kHz for both the ADC and

DAC signal chains. The TAC5301-Q1 supports timedivision

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, make TAC5301-Q1

an excellent choice for space-constrained automotive

systems.
