18SCT005

1200V Voltage Monitor

The 18SCT005 is a very accurate (+/-0.4%) voltage divider typically used to sense system voltage from +/-150V to +/-1200V. The nominal gain of 3125ppm is extremely constant with temperature and voltage varying by about 8ppm from -40 to 85C at 800V.

For systems using a voltage pump, the 18SCT005 has a built-in 1kHz low-pass filter eliminates noise from the effect of voltage pumping frequencies thus allowing accurate voltage measurements for portable systems using charge pumps.

The very small footprint of the TSSOP8 (4.4mm) makes this IC ideal for compact application where saving space is important but its linearity and constant
performance across temperature and voltage makes this the ideal choice for HV electronics in general.
