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