LTC2627CDEIDE - Dual 16-Bit I2C VOUT DACs with 10ppm/°C Reference

The LTC2627CDEIDE from Linear Technology is a highly precise dual 16-bit digital-to-analog converter (DAC) designed to deliver outstanding performance for a wide array of applications that require high-resolution digital-to-analog conversion. This product is housed in a compact, 12-lead DFN package, ensuring it is suitable for space-constrained applications.

One of the key features of the LTC2627CDEIDE is its integrated precision reference with a low temperature coefficient of just 10ppm/°C, ensuring stable and accurate output voltages over a wide temperature range. This makes it an ideal choice for high-precision industrial, automotive, and communication systems where temperature variations can significantly impact performance.

The DAC operates with a supply voltage range from 2.7V to 5.5V, providing flexibility for use in various systems with different power requirements. The LTC2627CDEIDE offers an I2C-compatible serial interface, which allows for easy communication with microcontrollers and other digital systems. This feature simplifies the integration process and reduces the complexity of the system design.

Each of the two DAC channels can be independently programmed using the I2C interface, giving designers the ability to set the output voltage to a desired level with high precision. The device also features a power-on reset circuit that ensures the DAC output powers up to zero volts and remains there until a valid write takes place. This feature is critical for applications where a predictable startup condition is required.

Furthermore, the LTC2627CDEIDE provides a generous output drive capability, making it suitable for driving heavy loads. The device also includes a power-down feature that reduces the power consumption to a mere 0.4µA, which is beneficial for power-sensitive applications.

In summary, the LTC2627CDEIDE from Linear Technology is a robust and reliable dual-channel 16-bit DAC that offers high precision, ease of use, and excellent temperature stability. Its compact size and feature set make it a versatile choice for a broad range of applications that demand the highest level of accuracy and performance.
