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.

♦ Wide (V

+ 2V) to +40V Supply Voltage Range

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

♦ Tight Initial Accuracy: 0.05% (max)

♦ Low Noise: 3.8µV

(typ at 2.5V Output)

P-P

♦ 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

Voltages

♦ 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 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 capaci-

tive loads up to 100µF. Eliminating the output bypass

capacitor saves valuable board area in space-critical

applications.
