Universal Preamplifier 14
UP14
-
For Two Dimensional Magnetic Recording (TDMR) and Heat-assisted Magnetic Recording (HAMR) Headamplifiers. Universal Preamplifier 14 (UP14) is designed for TDMR and HAMR Head Amplifiers. With new Guzik RWA4000 TDMR, UP14 allows to process signals from three Read Channels. It also supports two high speed data channels for Write data and Laser data. UP14 has two channels for dynamic TFC control and allows to program TFC power per sector and close loop TFC power control in each channel. UP14 can generate two programmable modulation signals for write data and laser data with bandwidth up to 20 MHz. UP14 consist of two boards. The first UP14 RW Board processes high-frequency signals: read-back signals, write data and laser data. The second UP14 Control Board provides power, control and low-frequency signal generation: TFC, write data modulation and laser modulation.

Current Sensors
-
A current sensor measures the flow of electric current to help optimize system performance, safety, and energy efficiency. They allow us to gauge how much power various parts are using. Whether it’s tracking motor loads in EVs, managing power in data centers, or monitoring energy in solar arrays, CTS sensors provide high-accuracy measurements with minimal phase shift.

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.

Current Sensing
-
voltage-output, current-sensing amplifier family that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device is a bidirectional, low- or high-side current-shunt monitor that allows an external reference to be used to measure current flowing in both directions through the internal current-sensing resistor sensor. The integration of the precision current-sensing resistor provides calibration equivalent measurement accuracy with ultra-low temperature drift performance and ensures an optimized Kelvin layout for the sensing resistor is always obtained.

Current Generator
MIG1260
-
MIG1260 is a current generator with wave shape 8/20 μs. The exact waveform delivered is a function of the surge generator and the impedance to which the surge is applied. The generator can deliver up to 60kA impulse current supported by 12kV impulse voltage, making it ideal for testing big varistors with high hold-on voltage. Mechanically the MIG1260 consists of one large rack and a separate control console with high voltage output terminals protected by a glass acrylic test cabinet.
