19-2300; Rev 3; 3/12 Ultra-High-Precision SOT23 Series Voltage Reference The MAX6033 ultra-high-precision series voltage reference features a low 7ppm/°C (max) temperature coefficient and a low dropout voltage (200mV, max). Low temperature drift and low noise make the MAX6033 ideal for use with high-resolution ADCs or DACs. This device uses bandgap technology for low-noise performance and excellent accuracy. Laser-trimmed, highstability, thin-film resistors, and postpackage trimming guarantee excellent initial accuracy (±0.04%, max). The MAX6033 consumes only 40µA of supply current and sources up to 15mA. Series mode references save system power and use minimal external components compared to two-terminal shunt references. The MAX6033 is available in the miniature 6-pin SOT23 package and is offered over the automotive temperature range (-40°C to +125°C).

Short OUTF to OUTS as close to the device as possible. Bypass OUTF with 0.1µF (min) capacitor to GND. 6 OUTS Voltage Reference Sense OUTS GND Figure 1. Precision Current Source Applications Information 3V SUPPLY Bypassing/Load Capacitance For the best line-transient performance, decouple the input with a 0.1µF ceramic capacitor as shown in the Typical Operating Circuit. Place the capacitor as close to IN as possible. When transient performance is less important, no capacitor is necessary. The MAX6033 family requires a minimum output capacitance of 0.1µF for stability and is stable with capacitive loads (including the bypass capacitance) of up to 100µF. In applications where the load or the supply can experience step changes, a larger output capacitor reduces the amount of overshoot (undershoot) and improves the circuit’s transient response. Place output capacitors as close to the device as possible. Supply Current The quiescent supply current of the MAX6033 series reference is typically 40µA and is virtually independent of the supply voltage. In the MAX6033 family, the load current is drawn from the input only when required, so supply current is not wasted and efficiency is maximized at all input voltages. This improved efficiency reduces power dissipation and extends battery life. When the supply voltage is below the minimum-specified input voltage (as during turn-on), the devices can draw up to 150µA beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on. Output-Voltage Hysteresis Output voltage hysteresis is the change in the output voltage at TA = +25°C before and after the device is cycled over its entire operating temperature range. Hysteresis is caused by differential package stress appearing across the bandgap core transistors. The typical temperature hysteresis value is 150ppm.

The turn-on time can increase up to 2ms with the device operating at the minimum dropout voltage and the maximum load. Precision Current Source Figure 1 shows a typical circuit providing a precision current source. The OUTF output provides the bias current for the bipolar transistor. OUTS senses the voltage across the resistor and adjusts the current sourced by OUTF accordingly. High-Resolution DAC and Reference from Single Supply Figure 2 shows a typical circuit providing both the power supply and reference for a high-resolution DAC. A MAX6033 with 2.5V output provides the reference voltage for the DAC. _______________________________________________________________________________________ 9 MAX6033 Ultra-High-Precision SOT23 Series Voltage Reference Ordering Information/Selector Guide (continued) OUTPUT VOLTAGE (V) TEMP COEFF (ppm/°C) INITIAL ACCURACY (%) TOP MARK MAX6033CAUT30-T 3.300 40 0.10 AAXI MAX6033CAUT30#TG16 3.300 40 0.10 #ACNH MAX6033AAUT41-T 4.096 10 0.04 ABDH MAX6033AAUT41#TG16 4.096 10 0.04 #ACNI MAX6033BAUT41-T 4.096 15 0.20 AAXN MAX6033BAUT41#TG16 4.096 15 0.20 #ACLG MAX6033CAUT41-T 4.096 40 0.10 AAXJ #ACNJ PART MAX6033CAUT41#TG16 4.096 40 0.10 MAX6033AAUT50-T 5.000 10 0.04 ABDI MAX6033AAUT50#TG16 5.000 10 0.04 #ACNK MAX6033BAUT50-T 5.000 15 0.20 AAXO MAX6033BAUT50#TG16 5.000 15 0.20 #ACNL MAX6033CAUT50-T 5.000 40 0.10 AAXK MAX6033CAUT50#TG16 5.000 40 0.10 #ACNM #Denotes a RoHS-compliant device that may include lead(Pb) that is exempt under the RoHS requirements.
