A digital potentiometer (or “digipot”) operates like a traditional mechanical potentiometer (pot), which is a variable resistor, except the digipot is an integrated chip (IC) that accepts signal input rather than the physical movement of a shaft or slide for adjustment. Essentially, both types of potentiometer are analog devices that provide variable resistance. However, a […]

Using the remote tuner solution from Maxim Integrated Products, Inc., designers can significantly simplify the head unit design of a vehicle and reduce cables. The MAX2175 RF to Bits tuner within the solution eliminates the need to rework the vehicle’s hardware to support worldwide radio standards, allowing updates by simply changing the vehicle’s software. Traditional radio architecture […]

Here, we review some common specifications for successive approximation register (SAR) and sigma delta analog to digital converters (ADCs.) For converters, resolution is the number of bits per conversion cycle that the converter is capable of processing. For example, a converter with 12 bits of resolution is often referred to as “12 bits wide,” since […]

STMicroelectronics has introduced three new sensors, the LIS2DS12 3-axis “pico” accelerometer, LSM6DSL/M 6-axis inertial module, and the new LSM303AH eCompass help track movement continuously with minimal impact on device battery life by performing various motion-related calculations efficiently on-chip instead of using the main system processor. Pre-embedded algorithms that include high-precision pedometer, step detection, step counting, […]

Stackpole’s popular CSRF Series of foil on ceramic carrier current sense chips have added a robust 2043 size part rated for 6 watts of power. The 2043 chip size has terminations on the longer edge of the chip which allows it to handle higher currents with lower thermal resistance and exceptional TCR of 50 ppm. […]

Temperature doesn’t change very quickly, and temperature sensors match that characteristic. Environmental temperature changes are generally slow, on the order of less than 0.1 sec/°C. Typical temperature sensors used in circuits are resistance temperature devices (RTDs), thermocouples, thermistors or integrated silicon sensors. Trade-offs amongst these devices include cost, cost to operate, response time, noise immunity, […]

Common-impedance coupling occurs when two or more circuits share a common ground and is the result of a shared impedance in a shared ground path. The best way to explain it is by way of a common example, such as when the lights dim when an air conditioner is turned on; they probably share the […]
