Data Acquisition is a process of measuring the physical state of a system, generally through the acquisition of electrical signals. Digital to Analog Converters or DAC are one of the major component blocks of this process, which converts digital information into an analog output. Among various DAC, LTC2604CGN-1#TRPBF, is a low power, quad, 12-bit voltage output DAC, with rail-to-rail output swing, excellent DC performance and fast settling time.

LTC2604CGN-1#TRPBF features a power-on reset to guarantee that all DAC outputs are in known states after power-up. Other features include an internal reference buffer which reduces the errors associated with printed circuit board (PCB) voltage drops. The device operates from a single +2.7 V to +5.5 V supply, and provides four digital input ports supporting SPI, QSPI, MICROWIRE, digital signal processor (DSP), and I²C serial interfaces.

The converter is built with zero crosstalk and SPI write latency, which simplifies operation and makes it suitable for multiple waveform generation and buffered current output applications. Its power dissipation makes it suitable for smartphone, tablet, portable and battery powered devices, while its single supply operation of +2.7 V to +5.5 V makes it a genuine rail-to-rail DAC.

These features make LTC2604CGN-1#TRPBF suitable for a wide range of application fields such as waveform generation, embedded control, automatic test equipment, instrumentation, process control, and industrial automation.

Working PrincipleThe LTC2604CGN-1#TRPBF is a 12 bit voltage output Digital to Analog Converter (DAC) that consists of a reference source and an array of voltage switch circuits. The digital value at the data inputs is converted to a proportional analog voltage at the output with the single reference. The inputs support both SPI, QSPI, MICROWIRE, DSP and I²C ports allowing easy interface with many digital devices.

The digital code word is loaded to the DAC register, and then it is transferred to the individual bin elements by DAC registers. Output switches are employed to achieve the DACs rail-to-rail range. The converter is build with +/-2 LSB DAC register accuracy, making it more accurate than most DACs in its class. The current source outputs eliminate external buffering and enable easy circuit integration.

The ability to load any of the data formats makes the device very flexible. It also offers a choice of zero or mid-scale reset functions for each output channel. As it requires very low power dissipation, the device can be powered from the standard +2.7 V to +5.5 V supply, making it suitable for battery powered and other portable applications.

In certain applications, LTC2604CGN-1#TRPBF is used for driving processors, A/D converters, DACs and analog switches. Its output voltage range can be set as individual channels and adjusted in 1mV increments up to 10V. This supports easy calibration, reduces installation time and ensures that each channel outputs the intended voltage even when the ambient temperature changes.

ConclusionThe LTC2604CGN-1#TRPBF is a low power, quad, 12-bit voltage output DAC with excellent DC performance, fast settling time and a single +2.7 V to +5.5 V supply making it suitable for a wide range of application fields, such as embedded control, waveform generation, process control and industrial automation. Thanks to its features including rail-to-rail output swing, power-on reset, internal reference buffer and several digital input support, it is one of the most popular Digital to Analog Converters.
