These devices do not require thin- film resistors, greatly lowering manufacturing complexity and cost. A 50ppm/ °C output temperature coefficient and a 15µA to 20mA operating current range make these devices at- tractive for multimeter, data acquisition converter, and tele- communication voltage references.
