ESCRIPTION
:
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.
