Tổng quan
Description
- What it is: A 14‑bit digital‑to‑analog converter (DAC) with a serial (SPI‑like) input, part of the DAC7614E family. It converts a 14‑bit digital word into an analog output (voltage or current, depending on configuration and external circuitry).
- Interface and control: Serial data input, clock, and chip‑select; may include LDAC (for simultaneous update) and CLR/SHDN pins for reset or power‑down.
- Key characteristics: monotonic operation with low glitch energy and good linearity, suitable for precision applications. Requires an external reference and an output stage (buffer/op‑amp for voltage output or a resistor for current‑output mode).
- Typical applications: instrumentation, calibration, test equipment, process control, waveform generation.
- How to use: supply power, connect a reference, drive the serial interface with a 14‑bit word, and issue an update to produce the corresponding analog output.
Note: exact specs (voltage/current output, reference options, temperature range) vary by revision; consult the datasheet for your specific part.
Equivalent
- Analog Devices AD5674R (quad 12-bit SPI, buffered outputs)
- Microchip MCP4924 (quad 12-bit SPI)
Note: exact pinout, reference, output range, and temp grade differ. For a precise one-to-one cross, use TI’s cross-reference tool or share your required specs.
Manufacturer
- What kind of company: An American multinational semiconductor company that designs, manufactures, and sells analog and digital integrated circuits.
Application
- Instrumentation and data-acquisition systems needing accurate analog voltages
- Process control and industrial automation for loop/drive signals
- Calibration, test, and measurement equipment
- Signal and waveform generation in lab/bench equipment
- Programmable bias, offset, and reference-voltage generation in embedded systems
- Sensor simulation for automotive, medical, and research devices
- Power-management and DC operating-point setting in precision analog circuits
Note: suitable for any application requiring multi-channel, high-accuracy D/A conversion.
