概述
Description
TLV5621IDR is a Texas Instruments 12-bit, voltage-output DAC with a SPI-like serial interface, housed in an 8-pin VSSOP package (IDR). It converts a digital word received over the serial bus into an analog voltage on VOUT, scaled by an external reference (VREF). Typical operation uses a 2.7–5.5 V supply.
Key points
- 12-bit resolution, voltage output
- SPI-compatible serial input (DIN, SCLK, CS); optional LDAC to latch updates
- External reference recommended (VOUT spans 0 to VREF)
- Low power, fast settling
- 8-pin VSSOP (IDR) package
Common uses
- Precision control and calibration in embedded systems
- Analog level setting for sensors, actuators, and test equipment
For detailed pinout, electrical specs, timing, and example circuits, consult the TLV5621IDR datasheet.
