AD1854JRSZ Datasheet/PDFThe AD1854JRSZ is a special-purpose data converter that combines high speed, low power dissipation and low power supply requirements. It is designed using the latest CMOS process technology and its encoder-assisted current input results in a low power-consumption of 2.2mW. The AD1854JRSZ allows the user to specify the resolution of the analog output by setting the number of bits used for the digital-to-analog conversion.
The AD1854JRSZ application field enables the device to be used for signal conversion and other tasks related to digital-analog signal processing. It is suitable for data acquisition systems, infrared detectors, spark ignition systems, power supplies, signal amplification and control systems, environmental monitoring, medical device applications and in other embedded applications which require high-precision and fast DAC operation.
The AD1854JRSZ is a multi-channel DAC system that combines several high-precision data converter integrated circuits into a single system. It integrates up to 8-parallel DAC channels with 10-bit resolution at up to 200MHz sampling rate, 8-channel switched-capacitor input data and a 1-channel serial-to-parallel port with four selectable input operating modes: single differential, differential serial, single ended, and transimpedance. The device operates from a 3.3 V or 5 V supply and offers a flexible and low power consumption operation.
The AD1854JRSZ is an integrated, high-performing, high-speed DAC which is ideal for applications needing high resolution and across a wide range of voltage outputs. The AD1854JRSZ also offers a high degree of linearity and dynamic range, high speed performance and low-power consumption, features that make it ideal for applications requiring maximum performance such as digital signal processing designs, digital controls, and industrial input/output systems.
The AD1854JRSZ working principle is based on current-mode conversion. A current-mode DAC consists of a database of switches and resistors, which can be controlled by a set of bits. Each time the DAC is put in a particular state, the corresponding current value is determined by the database. The current value can then be converted to a voltage using an analog receiver, and thus an analog output is provided.
The AD1854JRSZ features an advanced switching architecture which allows it to achieve faster speeds than previous current-mode DACs. By using an analog receiver, the current-mode architecture can provide a wide range of voltage outputs. In addition, the device has a wide dynamic range, low crosstalk, and high speed conversion capabilities, making it ideal for high sample rate applications and making it suitable for a wide range of embedded systems.
The AD1854JRSZ is a versatile DAC device that is suitable for a wide range of applications in data acquisition systems, power conversion, medical device applications, embedded systems, and other similar type applications. Due to its high-speed operation, low power consumption, wide dynamic range and linearity, the AD1854JRSZ is ideal for a myriad of applications requiring complex data conversion and manipulation faster than was ever possible before.
