+title: Maxim MAX1241 12-bit, single-channel analog to digital converter
+
+maintainers:
+ - Ioan-Alexandru Lazar <alazar@startmail.com>
+
+description: |
+ Bindings for the max1241 12-bit, single-channel ADC device. This
+ driver supports voltage reading and can optionally be configured for
+ power-down mode operation. The datasheet can be found at:
+ https://datasheets.maximintegrated.com/en/ds/MAX1240-MAX1241.pdf
+
+properties:
+ compatible:
+ enum:
+ -maxim,max1241
+
+ reg:
+ maxItems: 1
+
+ vref-supply:
+ description:
+ Device tree identifier of the regulator that provides the external
+ reference voltage.
+ maxItems: 1
+
+ spi-max-frequency:
+ maxItems: 1
+
+ shdn-gpios:
+ description:
+ GPIO spec for the GPIO pin connected to the ADC's /SHDN pin. If
+ specified, the /SHDN pin will be asserted between conversions,
+ thus enabling power-down mode.
+ maxItems: 1
+
+required:
+ - compatible
+ - reg
+ - vref-supply
+
+examples:
+ - |
+ #include <dt-bindings/gpio/gpio.h>
+ spi0 {
+ adc@0 {
+ compatible = "maxim,max1241";
+ reg = <0>;
+ vref-supply = <&vdd_3v3_reg>;
+ spi-max-frequency = <1000000>;
