In addition to mobile stations, the ADR280AKSZ-R2 is suitable for a variety of general-purpose applications. Most band gap refer-ences include internal gain for specific outputs, which simplifies the user’s design, but compromises on the cost, form factor, and flexibility. The ADR280, on the other hand, optimizes the band gap core voltage and allows users to tailor the voltage, current, or transient response by simply adding their preferred op amps.
The ADR280AKSZ-R2 operates on a wide supply voltage range from 2.4 V to 5.5 V. It is available in compact 3-lead SOT-23 and SC70 packages. The device is specified over the extended indus-trial temperature range of −40°C to +85°C.
