The ZSSC3008 sensor signal-conditioning IC is suited for resistive bridge sensor systems that require second-order linearity correction for a wide range of sensors. It offers a full complement of on-board diagnostics and protection features such as EEPROM signature, bridge connection checks, bridge input-short and open-bridge detection, power loss detection, and output current limits for short-circuit protection.
For sensor correction, the device employs offset correction and gain programming to precisely calibrate the bridge output signal. Additional features include a response time of typically 1 ms, an accuracy of 0.25 % over the –25° to 85°C range, and 0.5 % from –40° to 125°C, and a standard supply voltage of 2.7 to 5.5 V, or up to 30 V with external JFET. Depending upon configuration, current consumption typically ranges from 1 mA down to 250 µA. ($1.83 ea/1,000 — available now.)
