General Description
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.
