Summary:
TI's isolated loop power solution is a low-power, easy-to-implement isolated 4-20mA loop solution. This includes a 4-20mA driver with an integrated DAC and a small form factor transformer driver, and the combination of these two devices reduces the cost of ownership for the customer. The DAC161P997 provides a 16-bit DAC, a single-wire interface for traversing the isolation barrier, and high reliability for 4-20mA applications; the SN6501 is designed for a compact isolated power supply with minimal component count.
The main features of the solution:
- Small form factor transformer driver
- Provides primary voltage for isolated transformers and enables small form factor, low EMI, high efficiency isolated power paths
- 4-20mA output driver
- Integrated 16-bit DAC, single-wire interface for traversing isolation barriers, and high reliability for 4-20mA applications
