3 Description
The TAA5412-Q1 is a 2-channel high-performance,
audio analog-to-digital converter (ADC) that supports
analog input signals up to 10VRMS. The TAA5412-
Q1 supports line and microphone inputs, and
allows for both single-ended and differential input
configurations. This device offers an integrated highvoltage,
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
TAA5412-Q1 integrates an efficient boost converter
to generate a high voltage microphone bias using
an external, low-voltage, 3.3V supply, which is a
readily available supply in the system to generate
the high-voltage, programmable microphone bias.
The TAA5412-Q1 integrates the programable channel
gain, digital volume control, a low-jitter phase-locked
loop (PLL), a programmable high-pass filter (HPF),
biquad filters, low-latency filter modes, and allows
for sample rates up to 768kHz. The TAA5412-Q1
supports time-division multiplexing (TDM), I2S, or leftjustified
(LJ) audio formats, and can be controlled
with either the I2C or SPI interface. These integrated
high-performance features, along with a single, 3.3V
supply operation, make the TAA5412-Q1 device along
with TAC5xxx-Q1 device family an excellent choice for
scalable, space-constrained automotive systems. The
TAA5412-Q1 is part of a larger TAC5412-Q1 device
family, available for download at ti.com.
