High-Precision Voltage Reference with Temperature Sensor MAX6143
General Description
The MAX6143 is a low-noise, high-precision voltage reference. The device features a proprietary temperaturecoefficient curvature-correction circuit and laser-trimmed thin-film resistors that result in a very low 3ppm/°C temperature coefficient and excellent ±0.06% initial accuracy. The MAX6143 provides a TEMP output where the output voltage is proportional to die temperawww.DataSheet4U.com ture, making the device suitable for a wide variety of temperature-sensing applications. The device also provides a TRIM input, allowing fine trimming of the output voltage with a resistive-divider network.
