Analog Devices rolls highly accurate current sense amplifier
September 08, 2010 // Christoph Hammerschmidt
Analog Devices has introduced a new high-voltage amplifier for current sensing applications. The AD8207 zero-drift, high-voltage, bi-directional current sense amplifier meets the robust performance and quality requirements for motor and solenoid control in industrial and automotive applications. The vendor claims the device is the industry's most accurate current sense amplifier.
The product features temperature accuracy specified at a maximum of 1 μV/°C offset drift over the automotive temperature range of -40 degrees C to 125 degrees C. According to Analog Devices, this represents a 5-fold improvement over competing devices.
The architecture of the AD8207 accurately amplifies small differential current shunt voltages in the presence of rapidly changing common-mode voltages ranging from -4 V to 65 V. The new current sense amplifier rejects PWM (pulse width modulation) input common-mode voltages, while the zero-drift architecture yields the lowest offset drift performance available today.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.
This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android.
And the winners are...
In our previous reader offer, Pico Technology was giving away one of its recently launched PicoScope 3207B, a 2-channel USB 3.0 oscilloscope worth 1451 Euros. Lucky winner Mr L. Sanchez-Gonzalez from Spain should be receiving his PicoScope 3207B soon. Let's wish them some interesting findings with his projects.
