Frequently Asked Questions
How low is the supply current of the MAX920EUK+, and how does that extend battery life in always-on monitoring circuits?
The MAX920EUK+ draws a maximum bias current of 2 nA (0.002 µA) from the supply at 25°C. In a coin-cell battery-voltage monitor that operates continuously, this nanopower level allows a 220 mAh CR2032 cell to last over 10 years without any switching or sleep-mode management.
What input voltage range can the MAX920EUK+ handle relative to its supply rail?
The MAX920EUK+ supports beyond-the-rails inputs, meaning the differential input can exceed the 1.8 V supply by a defined margin. This allows it to compare signals from external voltage dividers or sensors whose output may momentarily overshoot the supply without latching up or damaging the device.
For a low-power system that already uses a 1.8 V regulator, how does the integrated reference in the MAX920EUK+ reduce component count?
The on-chip voltage reference eliminates the need for an external precision resistor divider or reference IC. This saves at least 2 passive components and reduces PCB area, which is critical in the 5-pin SOT-23 footprint measuring approximately 1.6×2.9 mm.
