REF192GSZ-REEL7 Integrated Circuits (ICs)

The REF192GSZ-REEL7 is a precision bandgap voltage reference that belongs to the family of ‘PMIC - Voltage Standby’ products. It provides exceptional accuracy over a wide temperature range and a very low temperature coefficient. The REF192GSZ-REEL7 can be used in a wide range of applications, such as powering digital systems, providing a reference voltage in A/D converters, voltage regulation and operational amplifiers, and providing a low temperature drift reference for systems requiring performance over varying environmental conditions.

The device operates by taking a voltage reference from a transistor-like structure, called a bandgap voltage reference. This structure is composed of a positive and a negative power input which are connected to the collector of two transistors. A small voltage drop appears across the collector-emitter junction of the two transistors. This drop varies depending on the temperature of the environment, the bias current, and the avalanche properties of the semiconductor junction. The voltage reference is obtained by using a pair of differential amplifiers to amplify and convert the reference voltage into a digital representation.

The REF192GSZ-REEL7 features a wide temperature range which enables it to be used in a variety of temperature-sensitive applications. Its rated temperature range is -40°C to +85°C, and its maximum recommended junction temperature is +150°C. This allows it to be used in harsh environments, such as industrial or automotive applications where wide temperature variations are expected. The REF192GSZ-REEL7 also features a wide supply range of 1.8V to 3.6V, making it suitable for a number of applications in both the commercial and industrial fields.

Another key feature of the REF192GSZ-REEL7 is its extremely low drift rates. Its drift rate over the specified temperature range is 0.4 µV/°C, which is significantly lower than any other voltage reference device. This low drift rate ensures that applications requiring a high degree of accuracy over a wide temperature range will benefit from using this device.

The REF192GSZ-REEL7 includes two enable/disable pins, allowing it to be used in a hot standby or enable/disable mode. This feature provides users with the flexibility to control the power sequence of their devices, as well as to enable/disable the voltage reference during operation. In Hot Standby mode, the REF192GSZ-REEL7 consumes typically 0.2µA, enabling the user to reduce power consumption when the device is not in use.

In summary, the REF192GSZ-REEL7 offers excellent accuracy and low drift rates over a wide temperature range, making it a suitable choice for most voltage reference-related applications.It has a wide supply range of 1.8V to 3.6V and includes enable/disable pins for additional flexibility. The device is well suited for commercial and industrial applications, particularly those that require good stability over varying environmental conditions.
