The • Very Low Power: 15 μW for 3 V Power DAC8832 provides excellent linearity (1 LSB INL), • High Accuracy, INL: 1 LSB low glitch, low noise, and fast settling (1.0 μS to 1/2 • Low Noise: 18n V/√Hz LSB of full-scale output) over the specified temperature range of –40 °C to +85°C. The output is • Fast Settling: 1.0 μS unbuffered, which reduces the power consumption • Fast SPI™ Interface, up to 50 MHz and the error introduced by the buffer. • Reset to Mid-Code This device features a standard high-speed (clock up • Schmitt-Trigger Inputs for Direct Optocoupler to 50MHz), 3 V or 5 V SPI serial interface to Interface communicate with a DSP or microprocessor. The DAC8832 provides unipolar or bipolar output (±VREF) when working with an external buffer, and is • Portable Equipment reset to mid-code after power-up. For optimum • Automatic Test Equipment performance, a set of Kelvin connections to the external reference and the analog ground input are • Industrial Process Control provided. • Data Acquisition Systems • Optical Networking The DAC8832 is available in a QFN-14 package, and is pin-to-pin compatible with the DAC8831IRGY, which is reset to zero code after power-up.
