3 Description

The TAC5111-Q1 is a low power Mono Codec with

2VRMS differential Input, 100dB Mono ADC and

2VRMS Mono DAC. The TAC5111-Q1 supports both

differential and Single-ended input and output. The

device supports both Microphone and Line In input on

the ADC Channel. DAC Output can be configured for

either Line Out or Head Phone Load. TAC5111-Q1

can drive up to 62.5mW into a Headphone Load.

The TAC5111-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, and allows for sample rates up to 768kHz.

The TAC5111-Q1 supports time-division multiplexing

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

can be controlled with I2C or SPI. These integrated

high-performance features, along with a single supply

operation, makes TAC5111-Q1 an excellent choice for

space-constrained audio applications.
