MAX6043 Precision High-Voltage Reference in SOT23 General Description Features +2.5V, +3.3V, +4.096V, +5.0V, or +10V Output The MAX6043 precision voltage reference provides Voltages accurate preset +2.5V, +3.3V, +4.096V, +5.0V, and +10V reference voltages from up to +40V input volt- Excellent Temperature Stability: 15ppm/C (max) ages. The MAX6043 features a proprietary temperature Tight Initial Accuracy: 0.05% (max) coefficient curvature-correction circuit and laser- Tiny SOT23 Package trimmed thin-film resistors that result in a very low tem- Wide +4.5V to +40V Supply Voltage Range perature coefficient of 15ppm/C (max) and excellent initial accuracy of 0.05% (max). Low temperature drift Low Noise: 4V (typ at 2.5V Output) P-P and low noise make the MAX6043 ideal for use with Short-Circuit Protected high-resolution A/D or D/A converters. Wide Operating Temperature Range The MAX6043 draws 320A of supply current and -40C to +125C sources 10mA or sinks 0.6mA of load current. The Stable with Capacitive Loads from 0 to 100F MAX6043 uses bandgap technology for low-noise per- No External Capacitors Required for Stability formance and excellent accuracy. The MAX6043 does not require an output bypass capacitor for stability, and Pin Configuration is stable with capacitive loads up to 100F. Eliminating the output bypass capacitor saves valuable board area TOP VIEW in space-critical applications. The supply-independent, low supply current makes the MAX6043 ideal for bat- + tery-operated, high-performance systems.
