AD5542ABCPZ-500RL7

AD5542ABCPZ-500RL7 is a 16-bit, serial input, unbuffered voltage output digital-to-analogue converter (DAC) that operates from a single 2.7V to 5.5V supply. Offering unbuffered outputs, the AD5542A achieves a 1μs settling time with low offset errors ideal for high-speed open loop control. The AD5542A incorporates a bipolar mode of operation that generates a ±VREF output swing. The AD5542A also includes Kelvin sense connections for the reference and analogue ground pins to reduce layout sensitivity. It is used in applications such as automatic test equipment, precision source-measure instruments, data acquisition systems, medical and aerospace instrumentation, and communication equipment.
