- * Texas Instruments LMP91000 series of potentiostats
- LMP91000: http://www.ti.com/lit/ds/symlink/lmp91000.pdf
- LMP91002: http://www.ti.com/lit/ds/symlink/lmp91002.pdf
- Required properties:
- - compatible: should be one of the following:
- "ti,lmp91000"
- "ti,lmp91002"
- - reg: the I2C address of the device
- - io-channels: the phandle of the iio provider
- - ti,external-tia-resistor: if the property ti,tia-gain-ohm is not defined this
- needs to be set to signal that an external resistor value is being used.
- Optional properties:
- - ti,tia-gain-ohm: ohm value of the internal resistor for the transimpedance
- amplifier. Must be 2750, 3500, 7000, 14000, 35000, 120000, or 350000 ohms.
- - ti,rload-ohm: ohm value of the internal resistor load applied to the gas
- sensor. Must be 10, 33, 50, or 100 (default) ohms.
- Example:
- lmp91000@48 {
- compatible = "ti,lmp91000";
- reg = <0x48>;
- ti,tia-gain-ohm = <7500>;
- ti,rload = <100>;
- io-channels = <&adc>;
- };
