Wed, 28 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6702277.html?rssid=233 Learn the thermal considerations so you don't get burned. Thu, 22 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6702268.html?rssid=233 You can create a 12-bit system using a 24-bit converter and eliminate the need for analog gain and level-shifting circuits. Thu, 22 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6703242.html?rssid=233 Various serial data standards require different clock specifications. Wed, 21 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6703183.html?rssid=233 Altium’s new NanoBoard 3000 embedded-system-development platform includes a board with an FPGA chip, an IR (infrared) remote control, and a 12-month license for Altium Designer schematic and FPGA software. Wed, 21 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6702709.html?rssid=233 Exar Corp’s new 5A XRP7704 and 16A XRP7740 quad-PWM (pulse-width-modulation)-controller chips include gate-driver circuitry that drives external FETs. Mon, 19 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6701649.html?rssid=233 Targeting LAN (local-area networks) and SAN (storage-area networks), Epson Toyocom recently announced the highly stable EG-4101/4121CA SAW (surface-acoustic-wave) resonator. Tue, 13 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6701497.html?rssid=233 Cissoid has introduced the Magma switching-power-supply PWM (pulse-width-modulator)-controller chip, which operates with 6 to 30V inputs and provides duty cycles up to 90%. Mon, 12 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6699737.html?rssid=233 The piecewise-linear step starts with a jerk, mindlessly follows a perfectly uniform ramp, and smacks hard into its upper limit. Real signals don't do that.
