3 Description

The TAC5111 is a low power Mono Codec with

2 VRMS differential Input, 100 dB Mono ADC and

2 VRMS Mono DAC. The TAC5111 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 can

drive up to 62.5 mW into a Headphone Load. The

TAC5111 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 768 kHz. The TAC5111

supports time-division multiplexing (TDM), I2S, or leftjustified

(LJ) audio formats, and can be controlled

with I2C or SPI. These integrated high-performance

features, along with a single supply operation, makes

TAC5111 an excellent choice for space-constrained

audio applications.
