Abstract: A analog integrated sensor device has an interface with only a single ground line and a single signal line configured to receive power and output an analog value. A power capacitor is coupled between the ground line and the single signal line. An analog sensor circuitry is operable to be powered by the power capacitor and further operable to output an analog output signal on the single signal line once the power capacitor has bee charged sufficiently.

Abstract: An input voltage range may be established between different voltage levels used for different programming functions of an integrated circuit device, thus implementing a protection zone (“safe zone”) of non-operation to facilitate prevention of an unintended irreversible programming operation, e.g., permanent write protection.

Abstract: A selectable gain amplifier in a standard integrated circuit package configuration comprises an amplifier having an analog input, an output and a control input for selecting one of two or three possible gains for the operational amplifier. A plurality of selectable gain amplifiers may be in a standard integrated circuit package configuration, each having a gain control input for selection of the two or three possible gains. The gain control input replaces an inverting input of a standard operational amplifier and the analog input is the a non-inverting input of the operational amplifier or visa-versa. All other characteristics of the selectable gain amplifier may be the same or similar to a standard operational amplifier. The selectable gain amplifier(s) may be packaged in industry standard integrated circuit packages having standard pin-outs so that they may be compatible as replacement analog amplifiers for existing technology operational amplifier integrated circuit packages.
