The MAX6220 is a low-noise, precision voltage reference with extremely low 20ppm/C temperature coefficient over the automotive temperature range (-40C to +125C) 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.
