MAX6173MAX6177 High-Precision Voltage References with Temperature Sensor General Description Benefits and Features The MAX6173MAX6177 are low-noise, high-precision Wide (V + 2V) to +40V Supply Voltage Range OUT voltage references. The devices feature a proprietary Excellent Temperature Stability: 3ppm/C (max) temperature-coefficient curvature-correction circuit and Tight Initial Accuracy: 0.05% (max) laser-trimmed thin-film resistors that result in a very low Low Noise: 3.8V (typ at 2.5V Output) P-P 3ppm/C temperature coefficient and excellent 0.06% initial accuracy. The MAX6173MAX6177 provide a Sources up to 30mA Output Current TEMP output where the output voltage is proportional Low Supply Current: 450A (max at +25C) to the die temperature, making the devices suitable for Linear Temperature Transducer Voltage Output a wide variety of temperature-sensing applications. The +2.5V, +3.3V, +4.096V, +5.0V, or +10V Output devices also provide a TRIM input, allowing fine trimming Voltages of the output voltage with a resistive divider network. Low temperature drift and low noise make the devices ideal for Wide Operating Temperature Range: -40C to use with high-resolution A/D or D/A converters. +125C The MAX6173MAX6177 provide accurate preset +2.5V, No External Capacitors Required for Stability +3.3V, +4.096V, +5.0V, and +10V reference voltages Short-Circuit Protected and accept input voltages up to +40V. The devices draw AEC-Q100 Qualified (Refer to Ordering Info Section 320A (typ) of supply current and source 30mA or sink for /V parts) 2mA of load current. The MAX6173MAX6177 use band- gap technology for low-noise performance and excellent Typical Operating Circuit accuracy. The MAX6173MAX6177 do not require an output bypass capacitor for stability, and are stable with (V + 2V) TO 40V INPUT OUT capacitive loads up to 100F. Eliminating the output bypass capacitor saves valuable board area in space- IN REFERENCE OUT critical applications. OUTPUT The MAX6173MAX6177 are available in an 8-pin SO * MAX6173MAX6177 * package and operate over the automotive (-40C to TEMP TRIM +125C) temperature range. GND Applications * *OPTIONAL.
