GENERAL DEscriptION

The SGM5349-16 is a 16-bit, 8 channels, voltage-output digital-to-analog converter (DAC). The chips are guaranteed monotonic by design.

The chips have a power-on control circuit, which can make sure DAC has a fixed output when system is powered on. The SGM5349A-16 outputs 0V when system powers up. The SGM5349M-16 outputs midscale when system powers up.

The chips have an nLDAC pin which can let DAC update outputs simultaneously.

The chips have an nCLR pin which can let DAC update to a configurable state, zero-code, midscale, or full-scale.

The SGM5349-16 uses a 3-wire SPI-compatible interface, and its operation data rate is up to 50MHz.

The SGM5349-16 is available in Green TSSOP-16 and TQFN-4×4-16L packages.
