Voltage references, also known as reference voltages, are used to provide a stable, predictable voltage level against which other voltages are compared. TLV431ACDBVTE4 is a programmable voltage reference from Texas Instruments. It can serve as a reference for a variety of applications in consumer and industrial systems.

The TLV431ACDBVTE4 features a 2.5V output and an adjustable reference voltage range from 2.5V to 15V with a maximum temperature coefficient of 10 ppm/degree C. It can be programmed and trimmed with a 10-bit DAC or single-pole, four-throw (SP4T) switch. The device also offers a low output-voltage drift of only 2.5 ppm/degree C and a wide common-mode input undervoltage lockout range.

TLV431ACDBVTE4 can be used in a variety of applications in consumer and industrial systems, including space-constrained applications. Its low voltage drift, wide VOCM range, and precision output voltage make it ideal for voltage reference and level-sensor applications. It is also suitable for portable and digital equipment, such as small LCDs, PDA, audio amplifiers, DC/DC converters, and other communication systems.

The TLV431ACDBVTE4 device operates a two-stage band-gap reference circuit and circuit-level accuracy adjustments. The two-stage reference architecture works to optimize the performance of the device across temperatureby combining the advantages of both the bipolar and MOS linear processes. This helps to provide a temperature coefficient of only 10 ppm/degree C, a wide common-mode input undervoltage lockout range, and a low output voltage drift of only 2.5 ppm/degree C.

In addition to its output accuracy, the device also comes with an internal gain of 0.
