LTC2631AHTS8-LM12#TRMPBF Digital-to-Analog Converter

The LTC2631AHTS8-LM12#TRMPBF is a high-performance, 12-bit digital-to-analog converter (DAC) from Linear Technology, designed to deliver precision and reliability for a wide range of applications. This component is part of a family of pin-compatible DACs, with resolutions ranging from 8 to 16 bits, providing designers with flexibility and scalability for their system designs.

Encased in a compact TSOT-23 package, this DAC features an integrated, high-accuracy reference with a 10ppm/°C max temperature coefficient, ensuring stable performance over a wide temperature range. The small form factor makes it ideal for space-constrained applications such as portable devices, while its low power consumption supports battery-powered systems.

The LTC2631AHTS8-LM12#TRMPBF operates on a single 2.7V to 5.5V supply and offers a rail-to-rail output, which allows the output to swing from 0V to Vcc. This capability provides maximum dynamic range and is particularly useful in single-supply operations where the full span of the supply voltage is utilized.

Communications with the DAC are enabled through a SPI/Microwire-compatible serial interface, which simplifies the digital interface and minimizes the number of I/O lines required from the controlling microprocessor or microcontroller. This feature is critical for systems with limited GPIO availability and helps in reducing the overall complexity of the circuit design.

The LTC2631AHTS8-LM12#TRMPBF also boasts a power-on reset function, which ensures that the DAC output powers up to zero-scale or mid-scale and remains there until a valid write takes place. This predictable startup behavior is essential for applications that require a safe initialization state, such as closed-loop control systems.

Additional features of this DAC include a shutdown mode that reduces the supply current to 0.4µA, which is particularly beneficial for power-sensitive applications. Whether used in process control, data acquisition systems, or digital calibration, the LTC2631AHTS8-LM12#TRMPBF from Linear Technology stands out for its precision, low power, and ease of use.
