A very high resolution DAC at 1kHz for space applications
In this paper a 24-bit Digital to Analog Converter using the ΣΔ modulation suitable for space applications is presented. This converter operates in the frequency range of 0.1 mHz up to 1kHz It features a current steering output stage consisting of 32 differential current sources. The device includes an I2C protocol which allows the selection of the Oversampling, Ratio of the converter to be either x128 or x256 for a 12 kHz or 6 kHz sampling ratio respectively. This circuit can be used either as a stand alone device or embedded into an ASIC as an IP core.
