MAXIM MAX6033 Technical data
General 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, highstability, 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).
