TLV431AID

The TLV431AID is an adjustable precision voltage reference product offered by Texas Instruments Inc. This product is mainly categorized as a PMIC – Voltage Reference and it is used in many applications where precision voltage reference is needed.

The main purpose of the TLV431AID is to provide a reference voltage to other components in a circuit. This product is ideal for designing circuits such as instrumentation amplifiers, analog-to-digital converters and operational amplifiers, where accurately regulated reference voltage is needed. It is also suitable for use in precision timing and monitoring circuits.

The TLV431AID operates on a few different principles. First, the external resistors are used to calibrate the output voltage. This allows users to select the exact voltage they require. Secondly, a bandgap voltage reference is used in combination with an integrated error amplifier to adjust the output voltage. This ensures that the reference voltage is kept stable, even as the temperature of the environment changes. Lastly, the output voltage is protected from transient over voltages using an over-voltage protection scheme.

The TLV431AID comes in a variety of configurations. The supplies can range from 2V to 36V, and the current can range from 100uA to 1mA. The accuracy of the output voltage is typically rated at 3ppm/°C over 0-70°C. Additionally, the operating temperature range of the device can extend from -40°C to 85°C.

One of the biggest advantages of the TLV431AID is that it is very small, with a package size of only 2mm x 2mm, which is ideal for being used in space-constrained applications. Additionally, it requires only a few external components for calibration, making it a very versatile product.

Overall, the TLV431AID is a great choice for applications that require a compact, accurate and reliable voltage reference. Its small size, low power consumption and stable output voltage make it ideal for use in precision analog and digital circuits.
