The ADFS5758 is a single-channel, 16-bit, current/voltage output DAC. The device is functional safety approved for unipolar current output and is a fully compliant item with a systematic capability of SC3, which can be used in safety-related applications up to SIL 2, according to IEC 61508. This arrangement allows a single ADFS5758 to be used to achieve SIL 2 for a nonredundant configuration. The safe state for the ADFS5758 is open circuit/high impedance.
The ADFS5758 is a single-channel, voltage and current output digital-to-analog converter (DAC) that operates with a power supply range from −33 V minimum on AVSS to +33 V
