LTC2854HDD#PBF – ANALOG DEVICES

The LTC2854HDD#PBF is a high-precision, low-power, 16-bit, current-output DAC from Analog Devices (formerly Linear Technology). This specific part number denotes a device in a 32-lead, 7x7mm QFN package. It operates from a single 2.7V to 5.5V supply, exhibiting a typical supply current of only 1.5mA. The LTC2854HDD#PBF features a ±0.5LSB integral nonlinearity and a settling time of <1µs to 0.01% of full scale, making it ideal for high-speed, high-resolution applications. Its current output, ranging from -10mA to +10mA, allows direct driving of loads without requiring an external amplifier, simplifying circuit design. _x000D_ _x000D_ The device incorporates a serial interface compatible with SPI, Microwire, and other common digital protocols, offering flexible integration. Common use cases include precision motor control, sensor excitation, and high-resolution waveform generation. Its low power consumption and high accuracy are significant advantages in battery-powered or space-constrained designs where minimizing component count and maximizing performance are crucial. The internal reference ensures high stability and eliminates the need for external reference components, further simplifying the bill of materials.
