MAX6143 High-Precision Voltage Reference with Temperature Sensor

Description

The MAX6143 is a low-noise, high-precision voltage reference. The device features a proprietary temperature-coefficient 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 temperature, 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. Low temperature drift and low noise make the MAX6143 ideal for use with high-resolution A/D or D/A converters.

The MAX6143 provides accurate preset +2.5V, +3.3V, +4.096V, +5.0V, and +10V reference voltages and accepts input voltages up to +40V. The device draws 340µA of supply current and sources 30mA or sinks 2mA of load current. The MAX6143 uses bandgap technology for low-noise performance and excellent accuracy. The MAX6143 does not require an output bypass capacitor for stability, and is stable with capacitive loads up to 100µF. Eliminating the output bypass capacitor saves valuable board area in space-critical applications.

The MAX6143 is available in an 8-pin SO package and operates over the automotive (-40°C to +125°C) temperature range.
