Ironwood Electronics has introduced the Imperium line of thermal control systems designed for temperature characterization of semiconductor devices across a range of −55 °C to +155 °C. The initial model supports devices with power dissipation below 10 W and achieves a temperature ramp rate of 80 °C per minute. The system is engineered to maintain […]
Analog IC Tips
Socket supports up to 40 GHz performance at –1 dB for high-frequency testing
Ironwood Electronics has released the Grypper chip‑size socket for 0.5 mm‑pitch BGA35 packages. Sized to match the target IC (“zero footprint”), the socket mounts directly on the same PCB area during reflow without expanding the board layout. The Grypper enables rapid device exchange for development, sorting, and failure analysis by allowing snap‑in insertion without a lid. […]

Power-supply supervisors keep circuits in check: part 1
Is my power supply OK? What about my microprocessor? What if something goes wrong? Simulations show what happens if DC voltage drops. Microprocessors can behave in unwanted ways when their power supplies don’t deliver the expected voltage. Errors can occur, circuits can unexpectedly reset or even go rogue. To prevent such problems, many devices use […]
Automotive Class-D amplifier operates -40 °C to +105 °C
Nuvoton has released the NAU83U25YG, an automotive-grade Class-D audio amplifier designed for vehicle electronics applications. The stereo amplifier delivers 3W output power into 4Ω loads or 1.7W into 8Ω loads, operating with digital I2S input signals and featuring I²C-controlled gain adjustment from 22 dB to -62 dB. The NAU83U25YG meets AEC-Q100 automotive qualification standards and […]
Ultra-compact op amp achieves 160 nA operating current
