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.
♦ Ultra-Low, 1ppm/°C Max Tempco
♦ Very Low, 1.5µVp-p Noise (0.1Hz to 10Hz)
(MAX6325)
♦ ±0.02% Initial Accuracy (MAX6350)
♦ ±15mA Output Source and Sink Current
♦ Low, 18mW Power Consumption (MAX6325)
♦ Industry-Standard Pinout
♦ Optional Noise Reduction and Voltage Trim
♦ Excellent Transient Response
The MAX6325 is set for a 2.500V output, the MAX6341
is set for a 4.096V output, and the MAX6350 is set for a
5.000V output. All three provide for the option of exter-
nal trimming and noise reduction.
♦ 8-Pin SO Package Available
♦ Low, 30ppm/1000h Long-Term Stability
♦ Stable for All Capacitive Loads
