Recording Ammeter
Amcorder
The Amcorder uses the same sensor technology as the original Ampstik. The True RMS inductive sensor does not use magnetic materials and has no moving parts. The opening of the sensor is electronically closed and external currents are electronically rejected. The accuracy, external current reject, and range of currents measured by the patented amp sensor substantially exceed the performance of the best clamp-on sensors. The key feature of the unit is the ability to leave it deployed on the line to record average current readings every 15 minutes for 30+ days. It easily attaches to the line with a standard shotgun style hot-stick. Once on the line, it immediately begins to collect and record the current load on the line.

Low Input Bias Current Amplifiers (<100 pA)
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

CCD Foundry Services
Teledyne DALSA Semiconductor’s 150mm CCD process offers surface or buried channel operation at up to 15V with two or three layers of polysilicon and one, two or three layers of metal. A modular processing approach allows our foundry customers to adjust process parameters to meet the most demanding requirements for CTE (>99.999%), charge storage capacity, and dark current (<1nA/cm2). The base process uses 1X projection lithography with 2.5µm design rules, allowing die sizes of up to 100mm X 100mm. Where required, tighter alignment tolerances and smaller feature sizes can be obtained by using 5X lithography, using a mix and match or all-stepper approach. The maximum die size attainable with the stepper is 22mm X 22mm, but larger sensors can be fabricated using stitching.
