REF4132B25DBVR

Product Overview

REF4132B25DBVR from Texas Instruments is a series voltage reference integrated circuit in a SOT-23-5 surface-mount package. It provides a fixed 2.5 V output from an input range of 2.55 V to 5.5 V, with a specified output current of 10 mA and a supply current of 100 µA. The device has an initial tolerance of ±0.05%, a temperature coefficient of 30 ppm/°C, and noise figures of 15 µVp-p over 0.1 Hz to 10 Hz and 24 µVrms over 10 Hz to 10 kHz. Its operating temperature range is -40°C to 125°C (TA).

Key Features

• Fixed 2.5 V series voltage reference output with ±0.05% initial tolerance.
• Input voltage range of 2.55 V to 5.5 V and 10 mA output current.
• The 30 ppm/°C temperature coefficient and 15 µVp-p noise from 0.1 Hz to 10 Hz contribute to stable reference behavior over the -40°C to 125°C (TA) operating range.
• A fixed 2.5 V output and 100 µA supply current are provided in a SOT-23-5 surface-mount package.
• Noise is specified as 24 µVrms over 10 Hz to 10 kHz.

Applications

• Precision analog-to-digital converter reference input in measurement and control electronics.
• Sensor signal conditioning circuits requiring a stable 2.5 V reference.
• Battery-powered instrumentation where the specified 100 µA supply current is relevant to low-power designs.
• Compact surface-mount boards using SOT-23-5 for fixed reference placement near ADCs or sensor interfaces.

Design & Procurement Notes

When selecting REF4132B25DBVR, verify that the available input voltage remains within 2.55 V to 5.5 V and that the required load current does not exceed the specified 10 mA output current. The fixed 2.5 V output and ±0.05% tolerance should be checked against the reference accuracy budget, while the 30 ppm/°C coefficient and 15 µVp-p / 24 µVrms noise values influence thermal stability and noise-sensitive analog circuitry. The SOT-23-5 surface-mount package and -40°C to 125°C (TA) operating range should be considered for PCB layout, thermal management, and placement near sensitive analog circuitry.
