But things were not working quite right, and (very) eventually a subtle misalignment was discovered. An earlier version of this blog contained an error – see ‘False start’ below This ...
Diodes has announced a single-channel version of its automotive-qualified AS2333Q dual precision micro-power op-amp. AS333Q has an 8μV input offset (22μV max 25°C), consumes 17μA, and has “near zero-drift over time and temperature for high-accuracy signal conditioning in automotive electronic control units”, according to the company. It has rail-to-rail inputs and output, with the common-mode range extending 100mV beyond the ...
Powerbox has announced PSU that generates 110Vdc from a train traction-voltage line (700-1,500Vdc) to start traction electronics when a rail vehicle’s own battery is below minimum operating voltage. The ‘Low battery voltage start’ (LBVS) is designed for high safety isolation, will come in different versions for different power requirements and will provide a stable voltage from two seconds up to 60 ...
