Fixed 4.096 V series reference for precision analog rails
The MAX6034AEXR41+T: This output voltage is a standard reference for 12-bit and 16-bit SAR ADCs and precision DACs — the 4.096 V rail sets the full-scale range directly without external scaling resistors.
Noise floor and dropout headroom
The input voltage range is 4.296 V to 5.5 V, meaning the reference requires only 200 mV of headroom above the 4.096 V output to maintain regulation — a 5 V rail with 5% tolerance (4.75 V min) provides comfortable margin. With a maximum 1 mA output current and 125 µA supply current, the part is suited for driving the reference input of a single ADC or DAC without a buffer — the load current stays well within the 1 mA ceiling.
SC-70-3 footprint and board integration
Housed in a 3-lead SC-70 (SOT-323) package with a 0.65 mm pitch, the MAX6034AEXR41+T occupies minimal board area — the footprint is roughly 2.0 mm × 2.1 mm, suitable for dense mixed-signal layouts where every square millimetre counts. The series reference topology means the load current is drawn from the input supply, not the output — the output capacitor (typically 0.1 µF to 1 µF) stabilises the loop; no external resistor divider is needed for the fixed 4.096 V output.
