LTC2668CUJ-12#PBF Digital-to-Analog Converter

The LTC2668CUJ-12#PBF is a high-precision, 16-channel, 12-bit digital-to-analog converter (DAC) component designed and manufactured by Linear Technology, which is known for its industry-leading solutions in the analog and mixed-signal semiconductor space. This product is a part of Linear Technology's extensive DAC portfolio and offers robust features that make it suitable for a wide range of applications, including automated test equipment, process control, and industrial automation systems.

Each of the 16 DAC channels in the LTC2668CUJ-12#PBF can be independently programmed via a serial peripheral interface (SPI), which provides flexibility and ease of use for system designers. The device operates with a supply voltage range of 2.7V to 5.5V, making it versatile for various power environments. The DAC outputs are buffered and can produce a 0V to Vref output span with a 1LSB INL (Integral Non-Linearity) performance, ensuring accurate and stable analog outputs.

The LTC2668CUJ-12#PBF comes in a compact 40-lead QFN package, which is suitable for space-constrained applications. The package is designed to minimize the footprint on the PCB, while still providing excellent thermal performance and ease of handling during the manufacturing process.

Key features of the LTC2668CUJ-12#PBF include:

• 16 independent DAC channels
• 12-bit resolution
• SoftSpan™ multiple output ranges: 0V to 5V, 0V to 10V, ±5V, ±10V, and -2.5V to 7.5V
• Guaranteed 16-bit monotonicity
• Integrated precision reference with low drift
• Channel-to-channel isolation
• Robust SPI interface with daisy-chain capability
• Power-on reset to zero-scale/mid-scale
• Thermal shutdown protection

With its high channel count and precision, the LTC2668CUJ-12#PBF is particularly well-suited for scenarios where multiple voltage levels need to be accurately controlled and where space is at a premium. Its robust design and integrated features make it a reliable choice for demanding applications that require high performance and long-term stability.
