The MAX6143AASA33+ is a low noise, high precision voltage reference with temperature sensor in 8 pin NSOIC package. The device has temperature coefficient curvature correction circuit and laser trimmed thin film resistors that result in a very low 1.5ppm/°C temperature coefficient and excellent ±0.06% initial accuracy. The MAX6143 provides TEMP output where output voltage is proportional to die temperature makes the device suitable for a wide variety of temperature sensing applications. It also provides TRIM input allowing fine trimming of output voltage with resistive divider network. Low temperature drift and low noise make MAX6143 ideal for use with high resolution A/D or D/A converters, digital voltmeters, voltage regulators and threshold detectors. The device draws 320μA of supply current and active-low shutdown feature reduces supply current to 0.01μA. The MAX6143 uses bandgap technology for low noise performance and excellent accuracy.
