Additional Infomation About Product

STEVAL-CCA023V1 Demonstration board for low noise microphone preamplifier with 2 V bias based on the TS472 Data brief Features Low noise: 10 nV / Hz typ. equivalent input noise F=1 kHz Fully differential input/output 2.2 V to 5.5 V single supply operation Low power consumption 20 dB: 1.8 mA Fast start up time 0dB: 5 ms typ. Low distortion: 0.1% typ. 40 kHz bandwidth -3 dB and adjustable gain Active low standby mode function (1A max) Low noise 2.0 V microphone bias output Available in flip-chip ECOPACK package and STEVAL-CCA023V1 QFN24 4x4 mm ESD protection (2 kV) RoHS compliant Description 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.
