1 / 7 page 1/7 s INPUT OFFSET VOLTAGE : 3mV max. OVER TEMPERATURE s FREQUENCY COMPENSATION WITH A SINGLE 30pF CAPACITOR (C1) s OPERATION FROM ±5V to ±15V s LOW POWER CONSUMPTION : 50mW AT ±15V s CONTINUOUS SHORT-CIRCUIT PROTEC- TION s OPERATION AS A COMPARATOR WITH DIFFERENTIAL INPUTS AS HIGH AS ±30V s NO LATCH-UP WHEN COMMON-MODE RANGE IS EXCEEDED s SAME PIN CONFIGURATION AS THE LM101A DESCRIPTION The UA748 is a general purpose operational am- plifier built on a single silicon chip. The resulting close match and tight thermal coupling gives low offsets and temperature drift as well as fast recov- ery from thermal transients. s Short-circuit protection s Offset voltage null capability s Large common-mode and differential voltage ranges s Low power consumption s No latch-up The unity-gain compensation specified makes the circuit stable for all feedback configurations, even with capacitive loads. However, it is possible to optimize compensation for best high frequency performance at any gain. The low power dissipa- tion permits high voltage operation and simplifies packaging in full-temperature range systems.
