DAC1243
Key Features
- PRELIMINARY The DAC1242/1243 are 12-bit digital-to-analog converters with 4-20mA current loop output
- The DAC1242 is a current-sinking device, while the DAC1243 provides true current sourcing into a ground referenced load
- Interfacing to other microprocessor families or larger puters requires only 1 or 2 TTL packages
- The device occupies 4 contiguous bytes of I/O or address space
- Null and span are internally calibrated to allow use of an external 100Q, 1% current-sensing resistor wit
