Data acquisition refers to the act of measuring various physical properties, such as temperature, pressure, vibration, and force, and then converting those measurements into digital or analog signals. This allows for data to be accurately stored or transferred to the appropriate device. Digital to analog Converters (DAC) are used in data acquisition systems when analog signals are required. One such type of DAC is the LTC1658CMS8#PBF.

The LTC1658CMS8#PBF is a precision, monolithic 8-bit digital-to-analog converter (DAC). It is designed to operate from a single 2.7V to 5.5V supply and is available in 14-lead TSSOP and SOIC packages. This DAC can operate at a conversion bandwidth up to 7.0 MHz and has a settling time of 15ns. It features a pipelined architecture, making it an ideal choice for demanding applications.

The LTC1658CMS8#PBF has a wide range of applications including waveform generation and waveform playback. It is also used in waveform analysis instruments, voltage-controlled oscillators (VCOs), analog-to-digital converters (ADCs), and programmable logic controllers (PLCs). Additionally, this device is suitable for use in medical systems, industrial automation systems, and data acquisition systems.

The working principle of the LTC1658CMS8#PBF is quite simple. It converts an 8-bit digital input code into an analog voltage. The device employs resistive-ladder conversion that is based on binary-weighted digital input codes. The output voltage is proportional to the binary input word and is calculated using the following formula:

VOUT = (D7.VREF/255) + (D6.VREF/127) + (D5.VREF/63) + (D4.VREF/31) + (D3.VREF/15) + (D2.VREF/7) + (D1.VREF/3) + (D0.VREF/1)

Where VREF is the reference voltage, D7...D0 are the 8-bit data input words, and VOUT is the output voltage. The reference voltage is provided by an external source and should be set to between 2.7V and 5.5V in order for the device to work properly.

The LTC1658CMS8#PBF is an excellent choice for applications requiring highest accuracy and lowest noise performance. This digital-to-analog converter offers superior accuracy, with an INL error of ±2 LSB max, over a wide temperature range of -40°C to +85°C. Additionally, it has a differential nonlinearity (DNL) better than 1 LSB and a low power dissipation of 500 μW.

In summary, the LTC1658CMS8#PBF is a precision, monolithic 8-bit digital-to-analog converter suitable for use in a variety of data acquisition applications. It features a pipelined architecture and a wide operating voltage range, making it an ideal choice for high-precision data acquisition systems. Its accuracy and low power dissipation make it suitable for applications where performance and power efficiency is essential.
