LTC2617IDE-1#PBF - A High-Precision Dual 16-Bit DAC from Linear Technology

The LTC2617IDE-1#PBF is a state-of-the-art dual 16-bit digital-to-analog converter (DAC) designed by Linear Technology, which stands out for its precision and versatility in various applications. This product is part of a family of dual 14-, 16- and 18-bit DACs, offering a perfect balance between high resolution and compact design.

Encased in a 14-lead DFN package, the LTC2617IDE-1#PBF is optimized for advanced systems that require high precision analog outputs. It operates with a supply voltage range from 2.7V to 5.5V, making it suitable for both 3V and 5V systems. The device features a full 16-bit performance without any missing codes and provides a highly stable output with a low noise level, which is critical for high-end instrumentation, industrial control systems, and automated test equipment.

The LTC2617IDE-1#PBF offers a multitude of features that enhance its usability and performance. It includes a precision internal reference with a 10ppm/°C max temperature coefficient, providing a stable and accurate voltage output. This internal reference is also buffered, which reduces the external component count and simplifies the design process. Additionally, the DAC has a user-selectable internal or external reference option, giving designers flexibility in their system design.

Each of the two DACs can be individually programmed via a simple 3-wire SPI/Microwire compatible serial interface, which can operate at clock rates up to 50MHz. The LTC2617IDE-1#PBF 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 particularly useful in systems that require a predictable startup condition.

Furthermore, the device supports a SoftSpan feature with five output ranges (0V to 5V, 0V to 10V, ±5V, ±10V, and –2.5V to 7.5V), allowing users to configure the output voltage range to match the needs of the subsequent stages in their signal chain without additional external components.

Linear Technology's LTC2617IDE-1#PBF is a powerful tool for designers who require high-precision DACs in their systems. Its combination of features and performance makes it an excellent choice for a wide range of applications that demand the highest level of accuracy and reliability.
