MAX6225/MAX6241/MAX6250

Low-Noise, Precision,

+2.5V/+4.096V/+5V Voltage References

General Description

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 high-resolution

data-conversion systems up to 16 bits.

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.
