Current Sense Amplifiers
-
Analog Devices’ current sense amplifiers offer excellent performance for a wide array of automotive and power management applications. These devices accurately amplify small voltages in the presence of large common-mode voltage, and provide high bandwidth, as well as level shifting and bidirectional capability. Excellent dc and ac accuracy over a wide temperature range from –40°C to +125°C minimizes errors in your measurement loop while not sacrificing on cost and package size.

Pulse Characterization Sensors
-
Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω

Current Mirrors
-
Analog Devices current mirrors are precision, high dynamic range, wide variable supply parts used for optical power monitoring, voltage biasing with current monitoring, and voltage-to-current conversion. Our current mirrors can monitor current down to as little as 3 nA and as much as 3 mA, with a linearity of 1% or better. The current dynamic range is 120 dB or 6 decades of current range, while the overcurrent protection feature in our devices forces the input pin to ground to avoid part damage. Over temperature (–40°C to +85°C) and process, the dynamic range only suffers 10 dB at the lower end of the range.
