MAX6174BASA+

Overview

The MAX6174BASA+ is a high-precision voltage reference providing a fixed +4.096V output with ±0.05% initial accuracy and a maximum temperature coefficient of 3ppm/°C. It accepts input voltages from (VOUT + 2V) up to +40V, drawing 320μA typical supply current while sourcing 30mA or sinking 2mA. The device includes a linear temperature sensor output proportional to die temperature and a TRIM pin for fine adjustment. It operates over the -40°C to +125°C automotive range in an 8-pin SO package.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure low noise and high precision.
• Integrated linear temperature transducer output provides voltage proportional to die temperature.
• TRIM input allows fine adjustment of the output voltage using a resistive divider network.
• Short-circuit protected output capable of driving capacitive loads up to 100μF without external stability capacitors.

Applications

• High-resolution A/D and D/A converters
• Automotive systems requiring AEC-Q100 qualification
• Digital voltmeters and threshold detectors

Procurement Notes

Verify the specific suffix against official documentation to confirm RoHS compliance and automotive qualification status. Ensure the ordering code matches the required tolerance grade and package variant. Confirm availability through authorized distributors as supply conditions may vary.

Selection Notes

Select this component when a stable 4.096V reference is needed alongside integrated temperature sensing capabilities. The wide input voltage range and low quiescent current make it suitable for space-constrained designs where external bypassing is undesirable.

Part Context

Part of the MAX6173–MAX6177 family of high-precision voltage references. These devices utilize band-gap technology to deliver excellent accuracy across a wide operating temperature range. The family shares identical pinouts and features, differing primarily in preset output voltage levels.
