LT1970A datasheet, cross reference, circuit and application notes in pdf format. dissipation issue with the LT1970. Lay out your copper heat sink carefully, and use at least 1 oz and preferrably 2 oz. copper on the board. If this is a "home use" lab supply, you also might want to consider that an LM12 will be easier to replace than an LT1970, meaning your power supply will be easier to service. the LT1970 power op amp to manage the operation, thanks to its built-in, closed-loop, current-limiting features. The four-quadrant supply provides at least ±16V adjustability with as much as ±2A output capability. Figure 1 shows the basic LT1970-based regulator section. Figure 2 shows the user- The LT1970 is a 500mA power amplifier with voltage programmable output current limit. Separate DC voltage inputs and an output current sensing resistor control the maximum sourcing and sinking current values. These control voltages could be provided by a D-to-A converter in a microprocessor controlled system. This uses the LT1970 as a linear driver of a DC motor with speed control.

The LT1970 has several advantages for a PXI power supply implementation, not the least of which being its small size and "on the fly" current limit, which is specifically helpful for ATE applications.

Current flow can remain continuous in one direction while the voltage across the sense terminals reverses in polarity. To see other chapters in this Application Note, return to the Introduction. Hello, I would like to develop a four quadrant power supply with a ammeter and voltmeter for photo voltaic VI measurement. when a current sensing resistor added in the series with the load in this setup it works fine in the lower voltage .But at voltage above 0.5V the output of LT1970 is oscillates.I need a closed loop circuit to make VI measurement.Is there any other method to develop a Four LT1970IFE#PBF ADI (Analog Devices, Inc.) are available at Bom-Components.
