MAX6173BASA+

The MAX6173BASA+ is a high precision voltage reference with temperature sensor in 8 pin NSOIC package. It features a temperature coefficient curvature correction circuit and laser trimmed thin film resistors that result in a very low ±3ppm/°C temperature coefficient and excellent 0.1% initial accuracy. The MAX6173BASA+ provides a TEMP output where the output voltage is proportional to the die temperature making the device suitable for a wide variety of temperature sensing applications. It also provides a TRIM input allowing fine trimming of the output voltage with a resistive divider network. The low temperature drift and low noise makes this device ideal for use with high resolution ADC or DACs. It uses bandgap technology for low noise performance and excellent accuracy. It does not require an output bypass capacitor for stability and are stable with capacitive loads up to 100μF. Eliminating the output bypass capacitor saves valuable board area in space critical applications.
