An LDO like T元17 is a simple, inexpensive power regulation and DC/DC converters with integrated power MOSFETs like TPS5410 offer highly integrated step down regulation. TPS40210) utilize external power MOSFETs for maximum design flexibility. For example, TI recently introduced the ISO1050, the world's first isolated CAN transceiver. TI is committed to provide solutions for both traditional and emerging industrial interfaces. In addition, wireless options such as ZigBee, Bluetooth, and other Low Power Wireless protocols are becoming more prevalent. Looking forward, designers are integrating mainstream wired interfaces such as Ethernet, USB, and CAN, into their products.

Common driver requirements are: offset 2MHZ.
Digital to Analog Converter: Low power, output voltage DACs with 12 to 18-bit resolution, sampling rate1 as in INA128 is recommended.Safety MCUs 12-bit ADCs, flexible HET Co-Processor and communication peripherals such as USB, Ethernet and CAN enable the MCU to act as a safe networked controller that can perform safe motor control as well. Safety MCUs are built to ease the development and certification of safety critical systems. 32-bit Digital Signal Controllers like F28235/28335 provide a high level of integration and embedded flash (up to 512kB), ultra fast ADC, communication ports, and a PWM control port.
The MSP430F24X family delivers low power consumption, wide supply-voltage range, programmable supply voltage supervisor and an internal reference ADC. TI offers a range of solutions for the control processor from the ultra-low power MSP430 microcontroller to the ARM® Cortex™-R4F-based Safety MCUs and C2000 Digital Signal Controllers (DSC) as well as Sitara™ and Integra™ microprocessors.

They leverage various sensor types and feedback mechanisms to monitor and control the local environment and system/machine interactions by collecting, storing and analyzing data. Programmable Logic Controllers (PLC) and Programmable Automation Controllers (PAC)Īre process and control implementations that cover everything from test labs and fabrication plants to military and medical electronics to basic data acquisition. A 0 is the least significant bit and A 3 is the most significant bit. Node A k (k=0,1,2,3….) is connected to reference voltage V R if input bit S k is 1 else, it is connected to ground.Schematic Block Diagram for Programmable Logic Controllers (PLC)
The R-2R ladder network circuit is shown below. However, it is difficult to fabricate an IC with widely varying resistance values (from R to 2 N−1R) and each with a small enough tolerance. The output voltage variation can be reduced by using resistors with a smaller tolerance. Since the inverting terminal of the Op Amp is at virtual ground,ĭrawback of DAC using binary-weighted resistors If the input bit S k is 1, A k gets connected to reference voltage V R else, it gets connected to ground. The graph between the output voltage and digital input is given below.Ĭonsider the DAC as shown in above figure. Where, K is proportional to the reference voltage V R. In general, DAC output voltage is given by The block diagram is shown below.įor a 3-bit DAC, with input S 2S 1S 0, the output voltage is given by An example of DAC: music stored in a DVD in digital format must be converted to an analog voltage for playing out on a speaker.Ĭonsider a DAC system having N-bit digital input and an analog output.
