♦ Low 1.0ppm/°C Temperature Coefficient
♦ Very Low 1.5µVp-p Noise (0.1Hz to 10Hz)
♦ ±0.02% Initial Accuracy
The MAX6225/MAX6241/MAX6250 are low-noise, preci-
sion voltage references with extremely low 1ppm/°C
temperature coefficients and excellent ±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 hig h-re s olution d a ta -c onve rs ion s ys te ms up to
16 bits.
♦ ±15mA Output Source and Sink Current
♦ Low, 18mW Power Consumption (MAX6225)
♦ Industry-Standard Pinout
♦ Optional Noise Reduction and Voltage Trim
♦ Excellent Transient Response
The MAX6225 is set for 2.500V output, the MAX6241 is
s e t for 4.096V outp ut, a nd the MAX6250 is s e t for
5.000V output. All three provide for the option of exter-
nal trimming and noise reduction.
♦ 8-Pin SO Package Available
♦ Low 20ppm/1000h Long-Term Stability
♦ Stable for All Capacitive Loads
