with software-programmable
input ranges
115ksps; up to ±12V bipolar input
range or down to 0 to 2.048V
unipolar range, ±16.5V overvoltage
protection (OVP)
Software-programmable input
ranges save design time and
eliminate external circuitry.
MAX1402/03 18-bit, 5-channel, sigma-delta
ADCs
4.8ksps, 0.75mW, 28-pin SSOP
package, matched current sources
for RTDs

require no R
SENSE
Sense resistor not needed,
hot-swaps 1V to 13.2V range of
supplies
Save cost and board space; single
device accommodates wide range
of supply rails.
MAX5932 Positive high-voltage, hot-swap
controller
Hot swaps wide 9V to 80V supplies;
overcurrent, overvoltage, and
undervoltage protection
One device accommodates
wide range of backplane supply
voltages.
