LTC2053/LTC2053-SYNC
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. V+ = 3V, V– = 0V, REF = 200mV. Output voltage swing is referenced
to V–. All other specifications reference the OUT pin to the REF pin.

The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. V+ = 5V,
V– = 0V, REF = 200mV. Output voltage swing is referenced to V–. All other specifications reference the OUT pin to the REF pin.
