The MAX6220 is a low-noise, precision voltage reference with extremely low 20ppm/°C temperature coefficient over the automotive temperature range (-40°C to +125°C) and excellent ±0.1% initial accuracy. This device features buried-zener technology for low noise performance. The load-regulation specification is guaranteed for source and sink currents up to 15mA. Excellent line and load regulation and low output impedance at high frequency make the MAX6220 ideal for high-resolution data-conversion systems up to 16 bits. The MAX6220 is set for 2.5V, 4.096V, and 5.0V outputs.
The MAX6220 voltage reference provides three selectable output levels (2.5 V, 4.096 V, 5 V) and is designed for automotive temperature ranges (‑40 °C to +125 °C). It uses buried‑zener technology to achieve very low noise (1.5 µV‑p‑p from 0.1 Hz to 10 Hz) and excellent line and load regulation.
Key electrical specifications include a ±15 mA source/sink current capability, an input voltage range of –0.3 V to +42 V, and a typical supply current of about 3.3 mA. The device is stable with capacitive loads up to 100 µF and offers optional external trimming for fine voltage adjustment.
