MAX6225/MAX6241/MAX6250 Low-Noise, Precision, +2.5V/+4.096V/+5V Voltage References General Description Features
The MAX6225/MAX6241/MAX6250 are low-noise, ● Low 1.0ppm/°C Temperature Coefficient precision voltage references with extremely low 1ppm/°C ● Very Low 1.5μVP-P Noise (0.1Hz to 10Hz) temperature coefficients and excellent ±0.02% initial ● ±0.02% Initial Accuracy accuracy. These devices feature buried-zener technology ● ±15mA Output Source and Sink Current for lowest noise performance. Load-regulation specifications ● Low, 18mW Power Consumption (MAX6225) are guaranteed for source and sink currents up to 15mA. ● Industry-Standard Pinout Excellent line and load regulation and low output impedance ● Optional Noise Reduction and Voltage Trim at high frequency make them ideal for high-resolution data-conversion systems up to 16 bits. ● Excellent Transient Response ● 8-Pin SO Package Available The MAX6225 is set for 2.500V output, the MAX6241 is ● Low 20ppm/1000h Long-Term Stability set for 4.096V output, and the MAX6250 is set for 5.000V ● Stable for All Capacitive Loads output. All three devices provide for the option of external trimming and noise reduction.
