多种空气燃料传感器控制接口

L9780 is an IC designed to interface a variety of wide range air fuel sensors.\n\n The device manages the oxygen pump of the wide range air fuel sensor by means of a voltage controlled current source (VCCS). The reference for the VCCS is generated by a PI controller with external compensation networ • Voltage controlled current source (VCCS) pump cell driver with selectable voltage clamp, offset compensation, diagnostic (short to battery) and 2 output channels \n• Impedance measurement of reference cell \n• 10-bit multiplexed A/D converter \n• Scaling amplifier with sample & hold and offset com;
