MAX6173BASA+TG002

Overview

The MAX6173BASA+TG002 is a high-precision voltage reference providing a fixed +2.5V output with ±0.1% initial accuracy and a maximum temperature coefficient of 10ppm/°C over the -40°C to +125°C range. It accepts input voltages from (VOUT + 2V) up to +40V, draws a typical supply current of 450µA, and sources up to 30mA or sinks 2mA. The device includes a linear temperature sensor output proportional to die temperature and a TRIM pin for fine adjustment via a resistive divider. It operates without an external output bypass capacitor for stability.

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 preset output voltage using a resistive divider network.
• Short-circuit protected output capable of sourcing 30mA or sinking 2mA load current.

Applications

• High-resolution A/D converters
• D/A converters
• Digital voltmeters
• Voltage regulators
• Threshold detectors

Procurement Notes

Verify the specific suffix 'TG002' against official Analog Devices documentation to confirm tape-and-reel packaging and any distinct handling requirements compared to standard tube variants. Ensure the component matches the MAX6173 family specifications for the 2.5V output variant. Confirm RoHS compliance status through manufacturer certificates prior to integration.

Selection Notes

Select this component when a stable 2.5V reference with integrated temperature sensing is required in space-constrained designs. The ability to operate without an output capacitor reduces board area. Verify that the 10ppm/°C temperature coefficient meets system accuracy requirements across the full automotive temperature range.

Part Context

This part belongs to the MAX6173–MAX6177 series of high-precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The series offers various fixed output voltages including 2.5V, 3.3V, 4.096V, 5.0V, and 10V. All devices share similar architecture featuring band-gap technology, low noise performance, and a common 8-pin SO package.

Replacement Considerations

Direct substitutes within the same family include other MAX617x variants with different fixed output voltages if the voltage level can be adjusted or if a different reference value is acceptable. Cross-family replacements require matching voltage, accuracy, and package constraints.
