Low-Noise, Precision, +2.5V/+4.096V/+5V
Voltage References
General Description
The MAX6225/MAX6241/MAX6250 are low-noise, preci-
sion voltage references with extremely low 1ppm/掳C
temperature coefficients and excellent 卤0.02% initial
accuracy. These devices feature buried-zener technolo-
gy for lowest noise performance. Load-regulation speci-
fications 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 provide for the option of exter-
nal trimming and noise reduction.
