General Description
The MAX6325/MAX6341/MAX6350 are low-noise, preci-
sion voltage references with extremely low, 0.5ppm/°C
typical temperature coefficients and excellent, ±0.02%
initial accuracy. These devices feature buried-zener
technology for lowest noise performance. Load-regula-
tion specifications are guaranteed for source and sink
currents up to 15mA. Excellent line and load regulation
and low output impedance at high frequencies make
them ideal for high-resolution data-conversion systems
up to 16 bits.
The MAX6325 is set for a 2.5V output, the MAX6341 is
set for a 4.096V output, and the MAX6350 is set for a
5V output. All three provide for the option of external
trimming and noise reduction.
