Precision and mixed signal applications usually require a voltage reference and at times several regulators or LDOs to support the analog circuitry. Separate regulators isolate the analog supply, digital supply and the voltage reference. The voltage reference supports the reference inputs of DACs and ADCs, and other devices that require a precise low noise voltage. The LT6658 satisfies the requirements of both, a voltage reference and regulator to provide an accurate voltage and enough current to supply power to sensitive precision analog blocks.View the Video
The LTC3649 step-down regulator combines key features of a high voltage buck regulator with a complete feature set that allows for ease of use in a variety of applications. The output voltage can be programmed with one resistor from ISET to GND, or it can be programmed directly with a voltage on the ISET pin. The LTC3649 accommodates a wide VIN and VOUT range of operation, and has the capability of monitoring and regulating on average output current as well as regulating on input voltage.View the Video

In this video, we will describe two unique features of this device that will allow you to greatly simplify your system. A flexible integrated digital filter makes it easy to trade off throughput for dynamic range and a novel digital interface supports slow serial communication.View the Video
In this short video we show an LED light demo to demonstrate the time synchronization capability of a SmartMesh IP Network. The fundamental technology that holds a SmartMesh IP Network together is time synchronization. All radio communication in the network is scheduled, and every node in the network has a precise sense of time. Time synchronization allow the network to exist, and that time information can also be used by the sensor.View the Video
Wireless Power enables applications where it is difficult or impossible to use a connector to deliver power. Examples include products that need to operate in harsh environments or need to be cleaned or sterilized as well as products that are simply too small for a connector. However, integrated solutions for the transmitter and receiver circuits usually involves relatively complex hardware and software design.
In this video, we show the LTC4125 – a full featured wireless power transmitter IC. Various high performance wireless power systems can be designed with an LTC4125 and one of several battery charger ICs in the Linear Technology portfolio as the receiver. With LTC4125 at the core of a wireless transmitter, most of the design complexity is reduced to determining the value of a few resistors and capacitors.View the Video
Hot Swap circuits are increasingly being used at power levels above 1000W. At these power levels multiple switch MOSFETs are required, but adding MOSFETs does not improve the power dissipation capability of the circuit when the current is regulated because the MOSFETs don’t inherently share current. The LTC4282 addresses this problem by dividing the MOSFETs into two parallel banks with independent current limits that enforce sharing between the two banks. This method doubles the SOA of an application while using the same number and type of MOSFETs of a traditional solution, allowing the use of less expensive MOSFETs with lower SOA.

Many common monitoring and control applications require multiple analog input signals to be simultaneously sampled and digitized, preserving time-domain correlation and frequency-domain phase relationships between the signals in the digital domain. The LTC2348-18 is designed specifically for these applications. The device simultaneously samples eight channels of high-voltage input signals and digitizes them using a high-performance 18-bit successive approximation register (SAR) analog-to-digital converter (ADC). It offers superb linearity, noise, DC precision, common-mode rejection ratio, and active crosstalk while converting all channels at 200ksps per channel throughput.

LEDs are being used in current luxury model automotive headlights. Future automotive headlight designs include more powerful LEDs, more LEDs, and highly animated and multifunctional LED strings. These “matrix” LED headlights have the ability to change brightness and patterns. They allow control of individual LEDs within a string and include new features that make LED headlights more distinguished and functional. The LT3965 matrix LED dimmer is used for matrix LED headlights. It is used to control the individual LED brightness for each LED within a string of LEDs. With computer I2C serial interface, patterns, fault diagnostics, and on/off or brightness control is possible. New automotive headlights that are more animated, robust and sophisticated are coming.
