GENERAL DESCRIPTION Aeroflex’s RHD5940 is a radiation hardened, single supply, 14-Bit Analog-to-Digital converter in a 24-pin SOIC package. The RHD5940 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single event latchup. These characteristics make the RHD5940 especially suited for the harsh environment encountered in Deep Space missions. It is guaranteed operational from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534 Class K, the RHD5940 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The RHD5940 takes an analog signal and performs a 14-bit successive approximation analog-to-digital conversion in a nominal period of 20uS. The 14-Bit digital output has a tri-state control allowing the connection of multiple RHD5940s. This provides the ability to interface many voltage readings to the digital processor data bus. The full-scale range is determined by reference input voltages which will typically include any ~ 4 volt span anywhere in the power supply range (nominal 5V supply). The input impedance of the reference/span terminals is a constant 4K ohms. Gain compression will occur near either power supply extremes but can be avoided if the references are more than 200mV away from the respective supply terminals. The input span can be less than 4 volts at the expense of ultimate resolution SCD5940 Rev A 1 page Pin # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Signal AIN NREF VCC STCNV_H OE_H CLK B00 B01 B02 B03 B04 B05 B06 B07 B08 B09 B10 B11 B12 B13 EOC_H BUSY_L VEE PREF Definition Analog Input Low Analog Reference Voltage Supply Voltage Start Conversion Output Enable Clock Input Digital Output 00 Digital Output 01 Digital Output 02 Digital Output 03 Digital Output 04 Digital Output 05 Digital Output 06 Digital Output 07 Digital Output 08 Digital Output 09 Digital Output 10 Digital Output 11 Digital Output 12 Digital Output 13 End of Convert Busy Supply Return High Analog Reference Voltage FIGURE 3: PACKAGE PIN-OUT AND SIGNAL DEFINITION SCD5940 Rev A Advanced 1/10/12 5 Aeroflex Plainview 5 Page
