The AD680 is a low power, low cost 2.5 V reference. It features low quiescent current, high accuracy, low noise and adjustable temperature coefficient.
The AD680 is a bandgap voltage reference designed for low power applications, offering a fixed 2.5V output from input voltages between 4.5V and 36V. It features a low quiescent current of 250 μA max and high accuracy with a maximum initial error of ±5 mV for AN and AR grades. The device is available in three package styles: 8-lead PDIP, 8-lead SOIC, and 3-pin TO-92.
