Data Acquisition - Digital to Analog Converters (DAC) are essential components which convert digital input signals to analog output signals. The LTC2634IMSE-HZ10#PBF is a highly integrated quad, 16-bit digital-to-analog converter (DAC) with integral non-volatile memory that stores the DAC settings and with a high degree of accuracy.

Application Field

This product is suitable for applications that require cheap, low-power and highly accurate digital-to-analog signals, such as DSP, data conversion, and process control. In addition to its general-purpose application, the LTC2634IMSE-HZ10#PBF also provides additional features that make it suited for automotive, instrumentation and industrial automation applications.

As an example, this DAC can be used in automotive battery management systems (BMS) to monitor and adjust the battery\'s energy level. It can also be used to regulate the voltage output of secondary cells in battery charging systems.

These features make the LTC2634IMSE-HZ10#PBF an ideal choice for industrial automation applications, including automated manufacturing systems and process control. Additionally, it can be applied to medical imaging systems, test equipment, precision instrumentation and communication systems.

Working Principle

The LTC2634IMSE-HZ10#PBF works in two modes: Unipolar mode and bipolar mode. In unipolar mode, the DAC output is proportional to the digital input, while in bipolar mode the DAC output is proportional to the digital input and the DAC offset value.

The output of this DAC is controlled by an N-bit digital input. A digital to analog (DAC) conversion is achieved by changing the DAC output voltage in proportion to the N-bit digital value. The digital value is provided through a serial interface. The digital input value may have a range from 0 to 255 (or from 0 to 127 in bipolar mode).

The output of DAC is stabilized by a chopper stabilization procedure. The chopper stabilization consists of the fusion of a reference voltage with an intermediate voltage. The output of this is a stable operational amplifier. The operational amplifier then provides an almost ideal output, free of high-frequency noise, even for huge temperature variations.

The LTC2634IMSE-HZ10#PBF can achieve an excellent level of precision and accuracy with a high sampling rate of up to 9MHz. The product also offers a number of features to ensure a smooth, low-noise digital-to-analog conversion, including a low-drift, low-noise reference, a low-drift, low-noise reference amplifier, a buffered output, slew-rate-limited outputs and current source and a power-down feature.

The LTC2634IMSE-HZ10#PBF is a robust device that is suitable for a wide range of digital-to-analog applications. It features an on-board EEPROM memory for non-volatile storage, allowing it to retain its settings even when power is removed. Its low-power consumption and fast sampling rate make it suitable for applications which require low latency and power-efficient operation. The device provides consistent and reliable performance over a wide temperature range, which makes it ideal for applications in challenging environments.
