DESCRIPTION:
Maxwell Technologies' 9240LP is a 14-bit, analog-to-digital converter that operates at a 10 MSPS rate. Manufactured with a high speed CMOS process, this ADC contains an on-chip, high performance, low noise, sample-and-hold amplifier and programmable voltage reference. The 9240LP offers single supply operation and dissipates only 480 mW with a 5 volt supply. This device provides no missing codes and excellent temperature drift performance over the full operating temperature range. The 9240LP utilizes Maxwell's LPTTM Latchup Protection Circuit. Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. 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 protection to 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class K.
