Digital to Analog Converter 07.26.07 Rev 1 FEATURES: •RAD-PAK® patented shielding against natural space radia- tion • Total dose hardness: - > 50 krad (Si), depending upon space mission • Excellent single event effects - SEL TH: > 120 MeV/mg/cm 2 - SEU TH: > 120 MeV/mg/cm 2 • Package: - 20 pin RAD-PAK® Flat Pack - 20 pin RAD-PAK® DIP • Low gain temperature coefficient: - 5 ppm/°C typ. • Fast interface timing • Single +5 V to +15 V supply DESCRIPTION: Maxwell Technologies’ 7545B is a 12-bit CMOS-buffered mul- tiplying DAC with internal data latches, which features a greater than 100 krad (Si) total dose tolerance, depending upon space mission. The 754B features a WR pulse width of 100 ns which allows interfacing to a much wider range of fast 8-bit and 16-bit microprocessors. It is loaded by a single 12-bit wide word under the control of the CS and WR inputs; tying these control inputs low makes the input latches transparent allowing unbuffered operation of the DAC. The 7545B is par- ticularly suitable for single supply operations and applications with wide temperature variations. Maxwell Technologies' patented RAD-PAK® packaging technol- ogy incorporates radiation shielding in the microcircuit pack- age. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK® provides greater than 50 krad (Si) radiation dose tolerance. This product is available with screening up to Class S. BLOCK DIAGRAM 7545B |
