Description
The LTC2758BCLX is a high‑precision 16‑bit multiplying digital‑to‑analog converter (DAC) from Linear Technology (now Analog Devices). It accepts a serial (SPI‑compatible) digital input and converts it to an analog output that can multiply a reference, enabling precise, programmable yields from a fixed reference. Key points:
- 16‑bit resolution with low noise, low drift, and fast settling.
- Serial interface for easy MCU/FPGA integration.
- Multiplying DAC capability (output proportional to code × reference).
- Suitable for precision control, calibration, instrumentation, and closed‑loop servo/applications.
- Single/dual supply operation with configurable output ranges and protection features.
- BCLX suffix denotes a RoHS/lead‑free package variant; exact package available in the data sheet.
For exact electrical specs, timing, and package details, refer to the LTC2758BCLX datasheet.
