MAX6033 Datasheet, PDF (1/11 Pages) Maxim Integrated Products – Ultra-High-Precision SOT23 Series Voltage Reference

19-2300; Rev 2; 6/03
Ultra-High-Precision SOT23 Series
Voltage Reference
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).
