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 0.06%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 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 (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 the output bypass capacitor saves valuable board area in space-critical applications.The MAX6173MAX6177 are available in an 8-pin SO package and operate over the automotive (-40C to +125C) temperature range.ApplicationsA/D Converters Voltage Regulators D/A Converters Threshold DetectorsDigital VoltmetersFeatures?Wide (V OUT + 2V) to +40V Supply Voltage Range ?Excellent Temperature Stability: 3ppm/C (max)?Tight Initial Accuracy: 0.05% (max)?Low Noise: 3.8V P-P (typ at 2.5V Output)?Sources up to 30mA Output Current ?Low Supply Current: 450A (max at +25C)?Linear Temperature Transducer Voltage Output ?+2.5V, +3.3V, +4.096V, +5.0V, or +10V Output Voltages ?Wide Operating Temperature Range: -40C to +125C ?No External Capacitors Required for Stability ?Short-Circuit ProtectedMAX6173MAX6177High-Precision Voltage References withTemperature Sensor_Maxim Integrated Products 119-3249; Rev 0; 5/04For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxims website at http:/www.wendangku.net/doc/c30d0356312b3169a451a4e1.html.Pin Configuration appears at end of data sheet.Ordering Information/Selector GuideTypical Operating CircuitM A X 6173M A X 6177High-Precision Voltage References with Temperature SensorABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
