REF195FS-REEL Integrated Circuits (ICs)

The REF195FS-REEL from Texas Instruments is a low-power, low-voltage voltage reference device in the PMIC – Voltage Reference category. It is a precision voltage reference family with a power supply range from 2.5 V to 18V. Its low operating current and wide operating temperature range (-40°C to +125°C) make it ideal for use in a variety of applications such as automotive, industrial, audio/video and instrumentation. This device is designed with the advanced manufacturing process, so the reference voltage is maintained at a low 0.05 % with temperature coefficient in between 0.3 and 5 ppm/°C.

The REF195FS-REEL provides two terminal reference devices such as two-terminal devices, Adjustable Voltage Reference (AVR) and Programmable Voltage Reference (PVR). The two-terminal devices can be used to keep a voltage reference constant regardless of temperature and power supply variations that might occur. It is able to maintain an output voltage that is a precise fraction of the supply voltage which helps in providing low drift reference in all the applications. The device offers four grades for different applications. It also provides factory-calibrated options for a variety of output voltage ranges.

The Adjustable Voltage Reference (AVR) and Programmable Voltage Reference (PVR) modules narrow the process of designing a voltage reference. It eliminates the need of dealing with external resistors or complicated pins. The AVR/PVR models have both common pin and address pin for setting the reference voltage for the device. Settings are available for output voltages from 2.5 V to 18 V. The AVR/PVR devices also feature a low current operational mode and an active-high shutdown feature.

The REF195FS-REEL offers an option to select a single voltage reference with one and two output reference configurations. The one output reference configuration allows only one reference output whereas the two output references can be used to set two different voltage levels. The two output references can be disabled and enabled independently with the help of control bits. The REF195FS-REEL also supports external trim adjustment. The device can also be used as an external voltage reference.

The REF195FS-REEL from Texas Instruments is an excellent solution for applications requiring both precision and low-power operations. The device is an ideal choice for applications that need precision and stability for the output voltage. Its ability to provide reference voltage without the need for external resistors and its low operating current makes it suitable for a variety of demanding applications. It is an ideal choice for automotive, industrial, audio/video, instrumentation, and many other applications that require precision voltage reference.
