You can build a precision absolute value circuit using two op amps and two precision resistors. If you use an op amp and an IC difference amplifier no user supplied precision resistors or resistor adjustments are required. Circuits shown are suitable for precision split supply operation and for single-supply operation. When used with a rail-to-rail op amp the single supply circuit can approach a

DDR Termination Regulator

An off-line two-switch forward is the best and cheapest topology when 266Wpeak, 190Wnom have to supply and audio amplifier. The universal input voltage is achieved by means of a switch.

Dual Motor Control and PFC Developer's Kit

The low-battery input (LBI) available on several step-down converters is often used to shut down the converter when the input voltage falls below a set threshold. This prevents damage to the battery and signals that the battery is at the end of its life and must be charged or replaced. Batteries have internal resistance that causes the voltage to drop as the load increases. This internal resista

Wide Input Range Converter delivers 5V at 2 Amps

Application Note 56 1.2V Reference

This PMP5714 is a non-isolated constant current LED driver that: from universal mains: delivers 20V…40V @ 700mA in a SEPIC topology: achieving high power factor in a small space.

This application note provides an indepth discussion of design references for A/D converters.

The MSP430x5xx series of devices is the latest addition to the MSP430 family of microcontrollers. Although there are many common features between the MSP430x5xx and MSP430x2xx/MSP430x4xx offerings, th

The PMP5637 is a reference design for a green adapter. It can operate from an universal input voltage range (85VAC to 265VAC).
