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.
