Description

The MAX6033 ultra-high-precision series voltage reference features a low 7ppm/°C (max) temperature coefficient and a low dropout voltage (200mV, max). Low temperature drift and low noise make the MAX6033 ideal for use with high-resolution ADCs or DACs.

This device uses bandgap technology for low-noise performance and excellent accuracy. Laser-trimmed, high-stability, thin-film resistors, and postpackage trimming guarantee excellent initial accuracy (±0.04%, max). The MAX6033 consumes only 40µA of supply current and sources up to 15mA. Series mode references save system power and use minimal external components compared to two-terminal shunt references.

The MAX6033 is available in the miniature 6-pin SOT23 package and is offered over the automotive temperature range (-40°C to +125°C).
