High-Precision Voltage Reference with

Temperature Sensor

General Description

Features

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.

♦ Excellent Temperature Stability: 3ppm/°C (max)

♦ Tight Initial Accuracy: 0.05% (max)

♦ Low Noise: 3.8µV

(typ at 2.5V Output)

♦ Sources up to 30mA Output Current

♦ Low Supply Current: 450µA (max at +25°C)

♦ Low 0.01µA Shutdown Current

♦ Linear Temperature Transducer Voltage Output

♦ +2.5V, +3.3V, +4.096V, +5.0V, or +10V Output

♦ Wide Operating Temperature Range: -40°C to

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

340µA of supply current and sources 30mA or sinks 2mA

of load current. The active-low shutdown feature (SHDN)

reduces supply current to 0.01µA. 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 100µF. Eliminating the output

bypass capacitor saves valuable board area in space-

critical applications.
