General Description
The MAX6143 is a low-noise, high-precision voltage ref-
erence. The device features 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 MAX6143 provides a TEMP output
where the output voltage is proportional to die tempera-
ture, making the device suitable for a wide variety of
temperature-sensing applications. The device also pro-
vides a TRIM input, allowing fine trimming of the output
voltage with a resistive-divider network. Low tempera-
ture drift and low noise make the MAX6143 ideal for use
with high-resolution A/D or D/A converters.
The MAX6143 provides accurate preset +2.5V, +3.3V,
+4.096V, +5.0V, and +10V reference voltages and
accepts input voltages up to +40V. The device draws
340A of supply current and sources 30mA or sinks 2mA
of load current. The active-low shutdown feature (SHDN)
reduces supply current to 0.01A. The MAX6143 uses
bandgap technology for low-noise performance and
excellent accuracy. The MAX6143 does not require an
output bypass capacitor for stability, and is stable with
capacitive loads up to 100F. Eliminating the output
bypass capacitor saves valuable board area in space-
critical applications.
The MAX6143 is available in an 8-pin SO package and
operates over the automotive (-40°C to +125°C) tem-
perature range.
