ZMD offers IC suitable for MEMS-based pressure sensors and liquid level gauges
ZMD
ZSSC3123 IC
ZMD has expanded its range of capacitive sensor signal conditioning devices with the wide-dynamic-range ZSSC3123 integrated circuit (IC), which is especially suitable for low-power, battery-driven sensor applications.
Delivering 14-bit resolution and 0.25 per cent accuracy over a range of sensor capacitances and temperatures, the chip is able to measure humidity, weight scales, load and compression sensing, as well as tension control.
According to the company, the device is particularly well suited for MEMS-based sensor elements, such as pressure sensors for hydraulic control systems, humidity sensors, and liquid level gauges.
The ZSSC3123 features an operating current as low as 60uA over the entire voltage range of 2.3–5.5V, as well as a built-in sleep mode that lowers the current consumption to <1uA for temperatures up to 85°C.
Unit prices start at €2.85 (approximately $3.82 or £2.46) each in 1,000-unit quantities.
