ALD1000

ALD1000  is a monolithic programmable voltage-tocurrent or voltage-to-voltage analog line driver circuit.It can convert a ±10V input into either an output voltage or current with remote sensing. ALD1000 provides drive for external transistors to boost output current to greater than ±25mA levels.Current and voltage sensing can be performed simultaneously.

Current sensing is achieved through a single external sense resistor. Voltage sensing is performed directly across the load. The logic inputs of ALD1000 provide for both output disable and switching between constant current or constant voltage output functions. An open collector output provides an error flag for open circuit loads. The output disable function allows full control of the output even during power-on and power-off sequencing. The ALD1000 instrumentation amplifiers are designed to insure that load noise is not circulated within the control loop.
