Manual-actuated QFN24 socket supports solderless device evaluation
Ironwood Electronics has released a test socket designed for QFN24 devices that uses a double-latch manual actuator. The socket is intended to support device evaluation, characterisation, screening, and other lab or production-adjacent test workflows where repeatable contact and quick device changeover are required. The double-latch actuation mechanism is designed to apply controlled compression during clamping, […]
Supercapacitors explained
Supercapacitors are a special type of electrochemical energy storage device noted for their ability to deliver sudden bursts of energy. Batteries typically provide the bulk energy required for sustained operation, whereas dielectric capacitors offer the rapid discharge rates necessary for filtering and pulse power. In such a scenario, supercapacitors address the gap between these two […]
4 GHz elastomer socket Introduced for BGA1440 with –1 dB insertion loss
Ironwood Electronics introduces a new elastomer-based socket solution targeting high-frequency BGA devices. The 94 GHz elastomer socket is designed for BGA1440 packages and enables signal paths with roughly –1 dB insertion loss at 94 GHz between each ball and the printed circuit board. The socket employs a swivel-lid compression mechanism to simplify device insertion and […]

The NMUX27518-Q100 is a bidirectional 6-channel 2:1 multiplexer, making it ideal for enabling memory expansion via a qSPI port in safety-critical in-vehicle applications like the advanced driver assistance systems (ADAS) domain controller, […]
Ultra-compact op amp achieves 160 nA operating current
ROHM Semiconductor announced the development of the TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) that achieves the industry’s lowest operating circuit current. Optimized for use as a sensing amplifier, this IC is ideally suited for space-constrained applications such as handheld measurement instruments, wearable devices, and indoor motion detectors. As the demand continues to grow for more sophisticated control […]
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 […]
Understanding ADC specs and architectures: part 5
ENOB describes an analog-to-digital converter’s performance with respect to total noise and distortion. In the earlier parts of this series on analog-to-digital converters (ADCs), we looked at the basics (part 1); gain error, offset error, and differential nonlinearity (part 2); integral nonlinearity (part 3); and then we looked at some ADC topologies and introduced AC […]
