The DS1004Z-2 is a small, low cost CMOS time delay line IC. It is a monolithic silicon IC set up as a delay line allowing up delays from 1.00μs to over 1.00s using off the shelf components. It is designed to be used in a wide variety of applications and is becoming more popular with circuit designers as a cost effective solution for their time delay applications.

Application Field

The DS1004Z-2 is widely used in many digital and analog systems for applications such as digital frequency synthesis, frequency synthesizers, clock/timing generators, frequency-hopping, and random frequency generators. It is especially suited for applications where fast response times are needed. In these applications, the DS1004Z-2 provides an accurate time delay with a wide range of delays available. Some other applications include audio clocking, motor speed controllers, and frequency dividers.

Working Principle

The DS1004Z-2 is built on a CMOS IC electronics circuit. This circuit provides the necessary impedance matching and signal shifting required for effective and reliable operation. The device consists of multiple stages called Delay Elements (DEs), with adjustable resistors to set the required delays. The delays are controlled by the DEs, which are connected in cascade and act as a controllable impedance buffer.

The time delay or cycle time accuracy is established by the characteristics of the controlling resistor. For example, a longer resistance will increase the cycle time accuracy, while a shorter resistance will decrease cycle time accuracy. The adjustable resistor is used to regulate the output signal in order to achieve the desired time delay. The DS1004Z-2 can also be configured to provide simultaneous and independent delays in multiple channels.

To select the desired delay time, the DS1004Z-2 has a switch or slider that manually sets the delay time. This is done by adjusting the resistance setting on the appropriate delay element. The adjustable resistor can also be controlled by an external analog voltage for applications requiring more control over the delay time.

The DS1004Z-2 is a CMOS-based device, making it ideal for low power consumption applications. In addition, the DS1004Z-2 is designed to operate using only a single supply, making it easy to use and minimize power consumption. Another advantage of the DS1004Z-2 is that it does not require an external clock, allowing for more flexibility when designing time delay systems.
