Product Overview
The TLV320ADC6140 is a Texas Instruments quad-channel audio ADC for Signal_Chain designs using analog microphones, line-in sources, or digital PDM microphones. It provides 4 analog input channels and supports up to 8 PDM microphone channels, with ADC sample rates from 8 kHz to 768 kHz.
For differential line and microphone inputs, the device specifies 123 dB dynamic range with DRE enabled, 113 dB dynamic range with DRE disabled, and -98 dB THD+N. ADC channel summing modes provide 116 dB dynamic range for 2-channel summing and 119 dB for 4-channel summing with DRE disabled. Full-scale input levels are 2 VRMS differential and 1 VRMS single-ended.
The device includes programmable channel gain from 0 dB to 42 dB in 1-dB steps, digital volume control from -100 dB to 27 dB, 0.1 dB gain calibration resolution, and 163 ns phase calibration resolution. It is supplied in a 24-pin WQFN (RTW) package with exposed thermal pad and operates across -40°C to 125°C ambient temperature.
