Matched quad high-performance low-voltage operational amplifier

The is a matched, low voltage, high performance quad operational amplifier. Among its unique input and output characteristics is the capability for both input and output rail-to-rail operation, particularly critical in low voltage applications. The output swings to less than 50mV of both rails across the entire power supply range. The NE/SA5234 is capable of delivering 5.5V peak-to-peak across a 600 load and will typically draw only 700A per amplifier. The bandwidth is 2.5MHz and the 1% settling time is 1.4s.


Output swing within 50mV of both rails Functionality to 1.8V typical Low current consumption: 700A per amplifier +15mA output current capability Unity gain bandwidth: 2.5MHz Slew rate: 0.8V/s Low noise: 25nV/Hz Electrostatic discharge protection Short-circuit protection Output inversion prevention

NOTES: 1. Each pin is protected by ESD diodes. The voltage at any pin is limited by the ESD diodes. 2. The differential input of each amplifier is limited by two internal diodes, connected in parallel and opposite to each other. For more differential input range, use differential resistors in series with the input pins. 3. The maximum operating junction temperature +150C. At elevated temperatures, devices must be derated according to the package thermal resistance and device mounting conditions. Derates above +25C: F package 6.7mW/C; N package 9.5mW/C; D package 6.25mW/C. 4. Simultaneous short circuits of two or more amplifiers to the positive or negative rail can exceed the power dissipation ratings and cause eventual destruction of the device. 5. Guaranteed by design.
