Datasheet Analog Devices MAX6220 — Datenblatt

19-1930; Rev 0; 4/01 Low-Noise, Precision, +2.5V/+4.096V/+5V
Voltage Reference
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. Applications Features
