SLASF30A January 2022 – December 2024 TAA5212
PRODUCTION DATA
For low power applications, the TAA5212 offers options to configure the device in a power tune mode with typical power consumption 5mW for 1-Channel and 8mW for 2-Channel recording for a 1.8V supply with a differential input dynamic range of 105dB. This mode can be configured by setting the PWR_TUNE_CFG0 (P0_R78) register to 0xD4. For power savings, the ADC modulator clock is set to run at 1.536MHz (the output data sample rate is multiples or submultiples of 48kHz) or 1.4112MHz (the output data sample rate is multiples or submultiples of 44.1 kHz) by using ADC_CLK_BY2_MODE (B0_P78_D[7]) register bit. In this mode, not all combinations of VREF voltages, common mode tolerance (ADC_CHx_CM_TOL) settings and input channel configuration (ADC_CHx_INSRC) settings are recommended. For more details refer the TAA52x2 Power Consumption Matrix Across Various Usage Scenarios application report for the supported input impedance, VREF voltages, common mode tolerance (ADC_CHx_CM_TOL) settings and input channel configuration (ADC_CHx_INSRC) settings in this mode.
