pA diodes protect sensitive inputs

Intended for protecting op-amp, sample-and-hold and multiplexer inputs, Linear Systems has created a range of extremely low-leakage picoamp diodes (PADs) with reveres currents ranging from 1pA to 100pA, which are “pin-for-pin replacements for Siliconix-Vishay”, said Linear. They are available in: TO-92 two-lead (part name = JPAD, 35Vmax reverse) TO-72 (PAD, 45Vmax) SOT-23 (SSTPAD 30V) DFN eight-lead ...

150Vin buck converter idles at 9µA

Analog Devices has introduced a 150V buck converter that draws 9µA quiescent – that is only 1.35mW wasted at full input voltage. Called LTC3894, its input range is 4.5 to 150V, and the the firm makes an interesting point: that this wide range can eliminate the need for external surge suppression devices on lower voltage rails. ...
