The Texas Instruments DAC121C085 is a 12-bit, single-channel, voltage-output digital-to-analog converter (DAC) designed for low power operation. It supports an extended power supply range from 2.7 V to 5.5 V and utilizes an I2C-compatible 2-wire interface, supporting standard (100-kHz), fast (400-kHz), and high-speed (3.4-MHz) modes.
This DAC offers a resolution of 12 bits with an integral non-linearity (INL) of ±8 LSB maximum and a differential non-linearity (DNL) of 0.6 / –0.5 LSB maximum. The output amplifier allows for rail-to-rail voltage output swing and achieves a settling time of 8.5 µs maximum. It ensures monotonicity to 12 bits.
In normal operation, the device consumes a typical power of 380 µW at 3 V and 730 µW at 5 V. In power-down mode, consumption is significantly reduced to 0.5 µW at 3 V and 0.9 µW at 5 V (typical). The DAC121C085 uses an external reference, providing a wide dynamic output range.
Available in a compact VSSOP (DGK) 8-pin package with a body size of 3 mm x 4.9 mm, the DAC121C085 is suitable for applications requiring precise voltage control in space-constrained designs. Its operating temperature range is -40°C to 125°C.
