This datasheet introduces the features and characteristics of the DAC7552, including a single supply of 2.7-V to 5.5-V, 12-bit linearity and monotonicity, rail-to-rail voltage output, 5 µs (maximum) settling time, 0.1nVs of ultralow glitch energy, -100 dB of ultralow crosstalk, 440 µA (maximum) of low power, 2 µA (maximum) of per-channel power down, power-on reset to zero scale, SPI-compatible serial interface (up to 50 MHz), daisy-chain capability, and asynchronous hardware clear.
The Texas Instruments DAC7552 is a 12-bit, dual-channel, voltage-output digital-to-analog converter (DAC) featuring exceptional linearity and monotonicity. It operates from a single 2.7-V to 5.5-V supply and utilizes a proprietary architecture to minimize transients such as code-to-code glitch and channel-to-channel crosstalk.
The device includes a 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 50 MHz. It features rail-to-rail voltage output capability, power-on reset to zero scale, per-channel power-down modes, and is available in a small 16-lead QFN package specified over an industrial temperature range of -40°C to 105°C.
