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
295 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 LPT™ 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 provid-
ing 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 avail-
able with screening up to Maxwell Technologies self-defined
Class K.
