5 V fixed reference with ±0.4 % initial accuracy
The MAX6105EUR+T: Initial output tolerance is ±0.4 %, which sets the DC accuracy floor for the ADC or DAC reference node without external trim. Output current is rated at 5 mA — enough to bias the reference input of a successive-approximation ADC and its input buffer, but not intended to power external loads beyond the reference pin itself.
Industrial temperature range and drift profile
Temperature coefficient is 75 ppm/°C typical, so the 5 V output shifts about 0.375 mV per 10 °C — budget this into the system error stack if the reference sees ambient swings. Supply current is 125 µA typical, low enough that the reference's own draw does not dominate the power budget in a battery-powered sensor node that sleeps between conversions.
Noise floor for precision signal chains
For a 16-bit ADC with a 5 V reference, the noise contribution from the reference sits below 1 LSB — the ADC's own noise floor and the layout's ground bounce will dominate the SNR budget.
SOT-23-3 footprint and supply posture
Housed in the common SOT-23-3 package (TO-236-3 / SC-59), the part fits a three-pin footprint shared by many series references — the pinout is standard for this class. Mounting is surface-mount, compatible with reflow profiles typical for small-outline packages. Lifecycle status is active, and the part is RoHS3 compliant.
