DESCRIPTION
The 18SCT005 is a very accurate (+/-0.75%) voltage divider typically used to sense system voltage up to +/-1200V. The nominal gain of 3125ppm is extremely constant with temperature and voltage varying by about 4ppm from -40 to 105C 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...
