LT385S8-1.2

The LM385S8-1.2 is designed as micropower voltage reference which is two terminal band gap reference diodes that for applications which require precision performance with micropower operation. The LM385S8-1.2 provides guaranteed operating specifications at currents as low as 15uA. Some additional features are maximum dynamic impedance of 1, low noise and excellent stability over time and temperature. The advanced design, processing and testing techniques make linear's LM385 series a superior choice over previous designs. Its typical applications include portable meter reference, portable test instrucments, battery operated systems, panel meters and current loop instrumentation.

LM385S8-1.2 has four features. (1)15uA to 20mA operating range, 1.2V version. (2)20uA to 20mA operating range, 2.5V version. (3)Guaranteed 1 dynamic impedance. (4)Very low power consumption. Those are all the main features.

Some absolute maximum ratings of LM385S8-1.2 have been concluded as follow. (1)Its reverse breakdown current would be 30mA. (2)Its forward current would be 10mA. (3)Its operating temperature range would be 0°C to 70°C. (4)Its storage temperature range would be from -65°C to 150°C. (5)Its lead temperature soldering 10 sec would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of LM385S8-1.2 are concluded as follow. (1)Its reverse breakdown voltage would be min 1.205V and typ 1.235V and max 1.260V. (2)Its average temperature coefficient would be typ 20ppm/°C. (3)Its minimum operating current would be typ 8uA and max 15uA. (4)Its reverse breakdown voltage change with current would be max 1.5mV for Ir<=1mA and would be max 25mV for Ir>=1mA. (5)Its reverse dynamic impedance would be typ 0.4 and max 1. (6)Its wide band noise (RMS) would be typ 60uV. (7)Its long term stability would be typ 20ppm/kHr. And so on.
