ZMDI’s ZSSC3122 is capacitive sensor signal conditioner with wide-dynamic-range and low power consumption. The chip delivers 14-bit resolution and 0.25% full-scale-output accuracy. The signal conditioning circuit has an operating current as low as 60 µA over the entire voltage range of 1.8V to 5.5V. A built-in sleep mode lowers current consumption to <1 µA for […]
