Triad Semiconductor’s TS4032 is a highly integrated, general purpose IC for space applications. It combines three basic building blocks required for a general-purpose system: measuring analog voltages from the various system sensors, two on-chip 11-bit DAC’s for driving actuators, and driving-receiving up to 8 digital IO signals. The analog sensing block is comprised of a 16-1 analog mux, a 14-bit Sigma Delta ADC, and two on-chip references (bandgap and DTMOS) and one off-chip reference input. The digital block is comprised of 8 General Purpose IO’s, 14-bit Decimation Filter, and a I2C-SPI Bus for reading and writing registers from the processor.
The TS4302 is available in a 144-pin BGA package (11mm x 11mm, 0.4mm pitch). The device operates from +3.0V to +3.6V and 1.62V to 1.98V supply inputs and is specified over a -55oC to +85oC operating temperature range.
