To meet these requirements of modern factory automation applications such as servo amplifiers and inverters, Toshiba has equipped the TLP7820 and TLP7920 with a delta sigma analogue-to-digital converter at the input side that is said to enable the devices to achieve a high level of linearity.
TLP7820 and TLP7920 are claimed to provide a guaranteed Common Mode Transient Immunity of 20kV/us, which is claimed to enable stable operation in electrically noisy environments and makes them suitable for motor control applications. Isolation is provided through an optical barrier with a guaranteed isolation voltage of 5000Vrms. Operating temperature range is -40 to 105°C.
A choice of two package types is available: TLP7920 is supplied in a DIP8 package; TLP7820 comes in an SO8L package, which is more compact, said to take up 30% less board space and featuring a 40% lower profile.
