Rectifier tracks positive and negative peaks
Texas Instruments Introduced Nano 125 nA IQ, 1% Accurate Voltage Supervisor, Push-Button Monitor with Programmable Sense and Reset Delay
Texas Instruments introduced nano-IQ, precision voltage supervisor TPS3899 that monitors system voltages or pushbutton inputs as low as 0.51 V...
Decibels: Use with caution
Decibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you may not think the same way...

10A H-Bridge Motor Driver ICs from Toshiba Fully Optimised for Automotive Deployment
Toshiba Electronics Europe has just announced two new driver ICs for brushed DC motors. The TB9054FTG and TB9053FTG utilise advanced DMOS FET technology to achieve a low RDS(ON) value...
Circuit breaker monitors leakage current
The residual-current circuit breaker continuously monitors the supply lines for any leakage current and immediately disconnects the supply if necessary. Load-supply wires, both live and neutral, pass through the magnetic core of the CR4311-5 transducer, which monitors the supply current...
Circuit provides flexible gain ranges
Certain designs need a programmable-gain amplifier with a wide gain range and high accuracy and common-mode rejection. Usually, it's wise to exploit a programmable-gain instrumentation amplifier, such as an AD625. Unfortunately, the gain range of such standard parts is fixed at certain values...
