描述 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.
