MAXIM MAX6165AESA+

The MAX6161–MAX6168 are precision, low-dropout, micropower voltage references. These three-terminal devices operate with an input voltage range from (VOUT + 200mV) to 12.6V and are available with output voltage options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. They feature a proprietary curvature-correction circuit and laser-trimmed thin-film resistors that result in a very low temperature coefficient of 5ppm/°C (max) and an initial accuracy of ±2mV (max). Specifications apply to the extended temperature range (-40°C to +85°C). The MAX6161–MAX6168 typically draw only 100μA of supply current and can source 5mA (4mA for MAX6161) or sink 2mA of load current. Unlike conventional shunt - mode (two - terminal) references that waste supply current and require an external resistor, these devices offer a supply current that is virtually independent of the supply voltage variation and do not require an external resistor. Additionally, the internally compensated devices do not require an external compensation capacitor. Eliminating the external compensation capacitor saves valuable board area in space - critical applications. A low - dropout voltage and a supply - independent, ultra - low supply current make these devices ideal for battery - operated, high - performance, low - voltage systems. The MAX6161–MAX6168 are available in 8 - pin SO packages.
