MAX6161BESA+

The MAX6161BESA+ is a precision, low dropout, micropower voltage reference in 8 pin NSOIC package. This three terminal device features a curvature correction circuit and laser trimmed thin film resistors that result in a very low temperature coefficient of ±15ppm/°C maximum and an initial accuracy of ±4mV. This device offers a supply current that is virtually independent of the supply voltage (8µA/V variation) and do not require an external resistor. It is an internal compensated device which does not require an external compensation capacitor. Eliminating the external compensation capacitor saves valuable board area in space critical applications. The low dropout voltage, independent supply voltage and ultra low supply current makes it ideal for battery operated and high performance low voltage systems. Typical applications include ADCs, notebook computers, PDAs, GPS, DMMs, cellular phones and precision +3V/+5V systems.
