**LTC2642ACDD-16#PBF: A 16-Bit Quad Voltage Output DAC with Precision and Versatility**

In the realm of high-performance digital-to-analog conversion, the **LTC2642ACDD-16#PBF** stands out as a premier solution for applications demanding exceptional accuracy and flexibility. This 16-bit, quad-channel voltage-output DAC integrates four precision digital-to-analog converters in a compact package, delivering robust performance across a wide range of industrial, automotive, and communications systems.

**Precision and Performance**

The LTC2642ACDD-16#PBF is engineered for **ultra-low noise and high accuracy**, featuring **16-bit resolution** with guaranteed monotonicity. Each of the four DAC channels provides a voltage output with **±1 LSB (max) INL and DNL errors**, ensuring reliable and precise analog signal generation. The device operates from a single 2.7V to 5.5V supply, making it suitable for both 3V and 5V systems. Its internal reference offers **2.5V or 4.096V options** with ±5mV initial accuracy, though it also supports external references for enhanced design flexibility.

**Versatile Interface and Control**

This DAC supports a standard **SPI-compatible serial interface**, enabling seamless communication with microcontrollers and digital processors. The interface includes daisy-chain capability, simplifying PCB layout and reducing control line count in multi-device configurations. The LTC2642ACDD-16#PBF also features a hardware-based **CLR function**, which asynchronously sets all DAC outputs to zero-scale or mid-scale, providing immediate response in critical situations.

**Robust Design and Applications**

Housed in a space-saving 10-lead DFN package, the device is designed for **high reliability in harsh environments**. Its low power consumption (0.5mA per DAC at 5V) and minimal glitch energy during updates make it ideal for precision instrumentation, automated test equipment, process control, and data acquisition systems. The quad-channel architecture allows simultaneous output updates, essential for multi-axis control and complex waveform generation.

**ICGOOFind**

The LTC2642ACDD-16#PBF combines **high resolution, multi-channel integration, and versatile operation** in a single IC, addressing the needs of advanced analog systems with efficiency and precision.
