LTC2616IDD#PBF - 16-Bit I2C/SMBus DACs with 10ppm/°C Reference

The LTC2616IDD#PBF is a high-precision digital-to-analog converter (DAC) from Linear Technology, designed to deliver exceptional performance for a wide range of applications requiring accurate digital control over analog outputs. This 16-bit DAC is part of Linear Technology's family of octal I2C VOUT DACs with integrated 10ppm/°C reference, ensuring stable and precise analog outputs over a broad temperature range.

Encased in a compact 12-lead DFN package, the LTC2616IDD#PBF offers a dual supply voltage range of 2.7V to 5.5V, making it versatile for both portable and stationary applications. The device features an I2C-compatible serial interface, which supports standard (100kHz), fast (400kHz), and high-speed (3.4MHz) modes, providing flexibility in communication speed according to system requirements.

With its integrated precision reference, the LTC2616IDD#PBF maintains a tight output accuracy of ±1LSB INL and DNL over the full operating temperature range of -40°C to +125°C. This ensures reliable and consistent performance for critical applications that demand high accuracy and stability, such as industrial automation, medical equipment, and telecommunications systems.

Each of the eight DAC channels can be individually programmed with a 16-bit resolution, allowing for fine-tuning of the output voltage to a maximum of VREF with a resolution of 15.25μV. The device also includes a Power-on Reset circuit that ensures the DAC output powers up to zero volts and remains there until a valid write takes place.

For added flexibility, the LTC2616IDD#PBF features a user-selectable internal or external reference. The internal reference has a low temperature coefficient, but if an application requires a different reference voltage or improved precision, an external reference can be used without compromising the DAC's performance.

Overall, the LTC2616IDD#PBF is a robust, high-precision DAC solution that offers ease of use, high integration, and the reliability expected from Linear Technology's products, making it an excellent choice for demanding applications that require precise analog control.
