MAX6225/MAX6241/MAX6250 Low-Noise, Precision, +2.5V/+4.096V/+5V Voltage References General Description Features The MAX6225 is set for 2.500V output, the MAX6241 is set for 4.096V output, and the MAX6250 is set for 5.000V output. All three devices provide for the option of external trimming and noise reduction. Ordering Information The MAX6225/MAX6241/MAX6250 are low-noise, precision voltage references with extremely low 1ppm/C temperature coefficients and excellent 0.02% initial accuracy. These devices feature buried-zener technology for lowest noise performance. Load-regulation specifications are guaranteed for source and sink currents up to 15mA. Excellent line and load regulation and low output impedance at high frequency make them ideal for highresolution data-conversion systems up to 16 bits.

Internally Connected. Do not use. 2 IN Positive Power-Supply Input 3 NR Noise Reduction. Optional capacitor connection for wideband noise reduction. Leave open if not used (Figure 2). 4 GND Ground 5 TRIM External Trim Input. Allows 1% output adjustment (Figure 1). Leave open if not used. 6 OUT Voltage Reference Output To augment wideband noise reduction, add a 1F capacitor to the NR pin (Figure 2). Larger values do not improve noise appreciably (see Typical Operating Characteristics). Noise in the power-supply input can affect output noise, but can be reduced by adding an optional bypass capacitor to the IN pin and GND. Bypassing The MAX6225/MAX6241/MAX6250 are stable with capacitive load values from 0F to 100F, for all values of load current. Adding an output bypass capacitor can help reduce noise and output glitching caused by load transients. Applications Information Negative Regulator Detailed Description Temperature Stability The MAX6225/MAX6241/MAX6250 are highly stable, low-noise voltage references that use a low-power temperature-compensation scheme to achieve laboratorystandard temperature stability. This produces a nearly flat temperature curve, yet does not require the power associated with heated references. The output voltage can be trimmed a minimum of 0.6% by connecting a 10k potentiometer between OUT and GND, and connecting its tap to the TRIM pin, as shown in Figure 1. The external trimming does not affect temperature stability. Figure 3 shows how both a +5V and -5V precision reference can be obtained from a single unregulated +5V supply. A MAX681 generates approximately 9V to operate the MAX6250 reference and MAX432 inverting amplifier. The +5V is inverted by the MAX432 chopper-stabilized amplifier. Resistor R1 is optional, and may be used to trim the 5V references. R2 and R4 should be matched, both in absolute resistance and temperature coefficient. R3 is optional, and is adjusted to set the -5V reference. 8V TO 36V INPUT 8V TO 36V INPUT IN IN NR MAX6225 MAX6241 MAX6250 OUT REFERENCE OUT * TRIM GND NR 10k 1F MAX6225 MAX6241 MAX6250 OUT REFERENCE OUT TRIM GND *OPTIONAL Figure 1.
