The STEVAL-CCA023V1 demonstration board is designed as an evaluation platform for the TS472 low noise microphone preamplifier with 2.0 V bias and active low standby mode. The board supports customization of the testing conditions, allowing the gain of the TS472 device to be adjusted, or an electret microphone to be biased either externally or using the TS472 built-in 2.0 V bias voltage.
The STEVAL-CCA023V1 is a demonstration board designed as an evaluation platform for the TS472 low noise microphone preamplifier. It supports customization of testing conditions, allowing users to adjust the gain or bias an electret microphone externally or using the built-in 2.0 V bias voltage.
The board features fully differential input/output and operates on a single supply from 2.2 V to 5.5 V. Key specifications include low noise (10 nV/√Hz typ.), low power consumption (1.8 mA @ 20 dB), and an active low standby mode function.
It serves as an evaluation platform for the TS472 low noise microphone preamplifier with a 2.0 V bias and active low standby mode.
The board has a low noise level of 10 nV /VHz typ. equivalent input noise at F=1 kHz.
The board draws a maximum of 1A when in active low standby mode.
