LTC2752ACLX#PBF: Dual 16-Bit SoftSpan I/Q DAC

The LTC2752ACLX#PBF is a high-performance, dual 16-bit digital-to-analog converter (DAC) from Linear Technology, designed to meet the rigorous demands of complex industrial, telecommunications, and test equipment applications. With its SoftSpan feature, the LTC2752ACLX#PBF offers five output ranges that can be independently programmed for each DAC channel, enhancing flexibility and precision in a variety of system designs.

This versatile DAC is equipped with a serial interface that supports high-speed SPI and MICROWIRE protocols, making it compatible with a wide range of microprocessors and digital signal processors. The LTC2752ACLX#PBF also includes a double-buffered data input structure, which allows for seamless updates to the DAC output, either synchronously or asynchronously, providing designers with increased control over signal generation.

Key features of the LTC2752ACLX#PBF include:

• 16-bit resolution for precise analog output
• Dual DAC channels with independent SoftSpan output ranges
• Programmable output ranges: ±10V, ±5V, 0-10V, 0-5V, and -2.5V to 7.5V
• Low glitch impulse of 1nV•s, minimizing spurious signals and noise
• Guaranteed monotonic over temperature for reliable performance
• High-speed serial interface compatible with SPI and MICROWIRE
• Asynchronous or synchronous DAC update capability
• Power-on reset to zero-scale or midscale, depending on the output range
• Thermal shutdown feature to protect the device from overheating

With its robust design, the LTC2752ACLX#PBF operates over the industrial temperature range of -40°C to 85°C, ensuring reliability in harsh environments. The product is available in a compact 7mm x 7mm QFN-48 package, which is ideal for space-constrained applications where board real estate is at a premium.

Whether used in automated test equipment, data acquisition systems, or digital communication systems, the LTC2752ACLX#PBF provides designers with a high-fidelity, dual-channel DAC solution that combines precision, programmability, and performance in a single integrated circuit.
