Linear Technology has a quad voltage output 16- and 12-bit digital-to-analogue converter (DAC) family with internal reference and I2C interface.

According to the supplier, the LTC2655 DACs achieve 16-bit performance of +4LSB INL maximum over temperature.

Offset error is +2mV (max) and gain error 0.1% (max).

Designed for use in multichannel, open loop and closed loop systems, the DAC’s integrated reference achieves 2ppm/°C typical and 10ppm/°C maximum temperature coefficient.

It comes in 20-pin 4mm x 4mm QFN and 16-pin narrow SSOP packages and operates from a single 2.7V to 5.5V supply and communicates via a 2-wire I2C compatible interface at up to 400kHz.
