Using Maxwell’s radiation-hardened RAD-PAK® packaging technology, the 7809LP has the same footprint as ADS7809 and is latchup protected by Maxwell Technologies’ Latchup Protection Technology (LPTTM). It is a 24 pin, 16-bit sampling analog-to-digital converter using state-of-the-art CMOS structures. The 7809LP contains a 16-bit capacitor based SAR A/D with S/H, reference, clock, interface for microprocessor use, and serial output dr...
