Voltage Reference
General Description
The MAX6220 is a low-noise, precision voltage refer-
ence with extremely low 20ppm/°C temperature coeffi-
cient 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 guar-
anteed 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.
