MAX6173–MAX6177 High-Precision Voltage References with Temperature Sensor General Description Benefits and Features
The MAX6173–MAX6177 are low-noise, high-precision ● Wide (VOUT + 2V) to +40V Supply Voltage Range voltage references. The devices feature a proprietary ● Excellent Temperature Stability: 3ppm/°C (max) temperature-coefficient curvature-correction circuit and laser-trimmed thin-film resistors that result in a very low ● Tight Initial Accuracy: 0.05% (max) 3ppm/°C temperature coefficient and excellent ±0.06% ● Low Noise: 3.8μVP-P (typ at 2.5V Output) initial accuracy. The MAX6173–MAX6177 provide a ● Sources up to 30mA Output Current TEMP output where the output voltage is proportional ● Low Supply Current: 450μA (max at +25°C) to the die temperature, making the devices suitable for a wide variety of temperature-sensing applications. The ● Linear Temperature Transducer Voltage Output devices also provide a TRIM input, allowing fine trimming ● +2.5V, +3.3V, +4.096V, +5.0V, or +10V Output of the output voltage with a resistive divider network. Low Voltages temperature drift and low noise make the devices ideal for ● Wide Operating Temperature Range: -40°C to use with high-resolution A/D or D/A converters. +125°C The MAX6173–MAX6177 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 320μA (typ) of supply current and source 30mA or sink ● AEC-Q100 Qualified (Refer to Ordering Info Section 2mA of load current. The MAX6173–MAX6177 use band- for /V parts) gap technology for low-noise performance and excellent

accuracy. The MAX6173–MAX6177 do not require an output bypass capacitor for stability, and are stable with (VOUT + 2V) TO 40V INPUT capacitive loads up to 100μF. Eliminating the output bypass capacitor saves valuable board area in space- IN critical applications. REFERENCE OUT OUTPUT The MAX6173–MAX6177 are available in an 8-pin SO * package and operate over the automotive (-40°C to
