Features • Self-centering 20 mA outputs • 12V operation • Norton amplifier • Function generator Description The LM1819 is a function generator/driver for air-core (moving-magnet) meter movements. A Norton amplifier and an NPN transistor are included on chip for signal conditioning as required. Driver outputs are self-centering and develop ±4.5V swing at 20 mA. Better than 2% linearity is guaranteed over a full 305-degree operating range. Applications • Air-core meter driver • Tachometers • Ruggedized instruments
