It can also be used for thermal sensors, high-voltage divider, low temperature coefficient filters and programmable gain elements.

Structure and Chip Design

Four resistor networks are integrated into thesame IPD package, connected incommon on one lead in a parallel structure.Each of the four resistor networks containseight resistors in a compact layout. Eachresistor is fabricated using a high-precision, polymer film, with up to nine different resistance values. Theresistor networks are arranged in an array layout, makingthe device size conveniently small.

The chip of the Y1719 is also designed to be user-friendly, making it easier to integrate into circuits and systems. It is based on a low-power design and the design ensures that it maintains a high-precision reading even when the voltage varies. The chip consists of a linear and programmable logic element, a precision current sensing resistor and an amplifier.

Working Principle

The Y1719 is designed to measure a wide range of currents with high accuracy. It works by measuring the voltage drop across a precision resistor. This voltage drop can then be used to calculate the current flowing through the resistor. The Y1719 also employs an automatic gain control (AGC) circuit which is used to measure the current more accurately regardless ofthe temperaturepphas changes. The AGC circuit also ensures that the sensing voltage is maintained well within the linear operating range. As the current increases, the voltage across the precision resistor increases. Therefore the voltage is kept in the desired range, and the readings remain accurate.

Conclusion

The Y1719V0469DB9L is one ofthe most widely used integrated passive devices. It provides precise performance in various applications and is suitable for operations at high temperatures. It also incorporates an AGC circuit which ensures accuracy in current readings and voltage. With a compact design, smaller scale usage and easy integration, the Y1719 is a great choice for a wide range of applications.
