The positive electrode of the galvanic cell is then connected to the Working pin of the LMP91000. The LMP91000 is then configured in 3-lead amperometric cell mode (as for amperometric cell). In this configuration the Control Amplifier (A1) is ON and provides the internal zero voltage. The transimpedance amplifier (TIA) is also ON, it converts the current generated by the gas sensor in a voltage, according to the transimpedance gain: Gain= RTIA If different gains are required, an external resistor can be connected between the pins C1 and C2. In this case the internal feedback resistor should be programmed to “external”. 20 Submit Documentation Feedback Copyright © 2011–2013, Texas Instruments Incorporated Product Folder Links: LMP91000 |
