LTC2053/LTC2053-SYNC e lecTrical characTerisTics The l denotes the specifications which apply over the full operatingtemperature range, otherwise specifications are at TA = 25°C. V+ = 3V, V– = 0V, REF = 200mV. Output voltage swing is referencedto V–. All other specifications reference the OUT pin to the REF pin.
