The MAX6173-MAX6177 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 MAX6173-MAX6177 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 MAX6173-MAX6177 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
320µA (typ) of supply current and source 30mA or sink
2mA of load current. The MAX6173-MAX6177 use
bandgap technology for low-noise performance and
excellent accuracy. The MAX6173-MAX6177 do not
require an output bypass capacitor for stability, and are
stable with capacitive loads up to 100µF. Eliminating the
output bypass capacitor saves valuable board area in
space-critical applications.
The MAX6173-MAX6177 are available in an 8-pin SO
package and operate over the automotive (-40°C to
+125°C) temperature range.
