The LTC2632CTS8-HI8#TRPBF is a digital-to-analog converter (DAC) used in data acquisition. It is a high voltage, 8-bit serial-input precision DAC which can operate from a single 4.5V to 16V supply. The output voltage is set via the I2C compatible serial interface which operates up to 5.5V. The I2C commuication is compatible with both 2-wire and 3-wire interfaces. The LTC2632CTS8-HI8#TRPBF offers a low power operation of 10μA, a fast settling time of 20μs for a full-scale step, and a monotonicity of 1/2LSB. The output range of the LTC2632CTS8-HI8#TRPBF is adjustable from 0V to either ±10V, ±5V, 0V-5V, or 0V-10V in single-ended mode. The device also provides an operational temperature range of -40°C to +125°C.

The applications of the LTC2632CTS8-HI8#TRPBF digital-to-analog converter (DAC) include signal conditioning, digital signal processing, data conversion, factory automation, and digital control. The device is suitable for applications where precision and accuracy are critical, such as closed-loop control, signal generation, and process control. The high voltage, 8-bit resolution, and adjustable 0 V–10 V range make it ideal for applications where high resolution and low noise performance are needed. The device is also well-suited for applications requiring flexibility in programming multiple I2C addresses for multiple DACs.

The working principle of the LTC2632CTS8-HI8#TRPBF is based on the mathematical operation of multiplying two digital numbers, one being the input word and the other a constant internal reference voltage set by the manufacturer. This action produces an output voltage that is directly proportional to the input word applied. The device takes a digital word as an input, and the internal reference voltage multiplies the input digital word to generate an analog voltage at the output. The output voltage range is determined by the design and depends on the internal reference voltage.

In addition, the LTC2632CTS8-HI8#TRPBF digital-to-analog converter (DAC) features an on-board voltage reference that offers a low drift performance, typically 0.1 %/°C maximum. The device also includes an auto-zero circuit that cancels non-linearities and offsets in the DAC transfer characteristics. The internal voltage reference is user-trimmable and capable of providing adjustment for different operating temperature range and supply conditions. The LTC2632CTS8-HI8#TRPBF also offers a low glitch of 20nV•s typical and a low power consumption of 10 μA typical.

Finally, the LTC2632CTS8-HI8#TRPBF digital-to-analog converter (DAC) is engineered to have low thermal errors, wide linear dynamic range, and excellent temperature and load-regulation characteristics. The device is equipped with an internal 3V regulator that enables the DAC to source or sink up to 18mA of output current at the output. With its wide range of applications, the LTC2632CTS8-HI8#TRPBF can be used in a variety of applications where accuracy, reliability, and high performance are required.
