The REF198ES is a voltage reference IC from Texas Instruments that is designed for precision applications. It is part of the precision voltage reference family of products developed to meet the highest performance criteria of industrial and automotive applications. The REF198ES has a low output impedance, highly accurate temperature tracking, and low power dissipation when compared to other voltage references.
The REF198ES is an ideal voltage reference for precision voltage reference applications such as industrial power supplies, automotive power systems, and embedded system designs. It provides a highly accurate and stable reference voltage that is not affected by line, load, or temperature variations. The REF198ES has a wide operating temperature range and provides excellent line regulation characteristics. It is available in both commercial and automotive grade options.
The REF 198ES has been designed for easy integration into a wide variety of systems. It has a built-in shutdown function, a wide input voltage range, and configurable output currents for multiple output configurations. The ICs have separate shutdown lines for each output to provide flexibility in how current is drawn from the output. In addition, the ICs are designed to operate with a minimum of external components, eliminates the need for expensive adjustment circuits.
The REF 198ES utilizes a precision voltage reference with an output of either 1.25V, 1.50V, or 1.75V and a wide line regulation range of 0.01% typical. The output voltage is maintained over a temperature range of -40°C to 85°C. The REF 198ES also provides excellent line regulation characteristics and can maintain the reference voltage over a wide input voltage range of 5V to 40V. In addition, the IC provides ultra-low power consumption at just 0.5W.
The REF 198ES offers a low frequency noise (LFN) measurement which ensures that the reference voltage remains stable even under transient conditions. The LFN measurement is also useful for comparing multiple reference ICs or measuring the stability of a given reference IC. The REF 198ES features a built-in self-test (BIST) feature which provides an on-chip testing capability for verifying the accuracy of the calibration.
The REF 198ES is designed to operate with a minimum of external components and requires an external reference bypass capacitor for proper operation. It also requires two resistors for its output configuration, and the operating temperature range can be further extended by selecting an optional external heater resistor to compensate for temperature-related drifts. The REF 198ES is also capable of higher current outputs than other voltage reference ICs, making it suitable for applications requiring a low power, high-quality voltage reference.
In conclusion, Texas Instruments\' REF 198ES is a high-performance voltage reference IC that provides an accurate output voltage and excellent temperature tracking. Its simple integration, low power consumption, and extended operating temperature range make it an ideal choice for precision applications. The REF198ES is available in both commercial and automotive grades, and its unique low noise measurement makes it suitable for measuring the stability of voltage references or comparing multiple reference ICs for critical applications.
