1、MAX6176AASA中文资料General DescriptionThe MAX6173MAX6177 are low-noise, high-precision voltage references. The devices feature 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
2、.06%initial accuracy. The MAX6173MAX6177 provide a TEMP output where the output voltage is proportional to the die temperature, making the devices suitable for a wide variety of temperature-sensing applications. The devices also provide a TRIM input, allowing fine trimming of the output voltage with
3、 a resistive divider network. Low temperature drift and low noise make the devices ideal for use with high-resolution A/D or D/A converters.The MAX6173MAX6177 provide accurate preset +2.5V,+3.3V, +4.096V, +5.0V, and +10V reference voltages and accept input voltages up to +40V. The devices draw 320A
4、(typ) of supply current and source 30mA or sink 2mA of load current. The MAX6173MAX6177 use bandgap technology for low-noise performance and excellent accuracy. The MAX6173MAX6177 do not require an output bypass capacitor for stability, and are stable with capacitive loads up to 100F. Eliminating th
