General Description

The MAX6033 ultra-high-precision series voltage refer-

ence features a low 7ppm/°C (max) temperature coeffi-

cient 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 per-

formance 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 sys-

tem power and use minimal external components com-

pared to two-terminal shunt references.

The MAX6033 is available in the miniature 6-pin SOT23

package and is offered over the automotive tempera-

ture range (-40°C to +125°C).
