STMicroelectronics STEVAL-CCA023V1 Demonstration Board Data Sheet
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.
