16-Channel 12-Bit Bipolar Voltage-Output DAC with 14-Bit Increment Mode
The AD5516 is a 16-channel 12-bit bipolar voltage-output DAC packaged in 74-ball CSPBGA. The part contains a special Increment/Decrement mode which allows 14-bit resolution to be achieved. The output voltage range is fixed at ±2.5 V (AD5516-1), ±5 V (AD5516-2) and ±10 V (AD5516-3). The DAC registers are written to via the 3-wire serial interface. The serial interface is compatible with standard SPI™, MICROWIRE™ and DSP interface standards and operates at clock rates up to 20 MHz. Access to the feedback resistor in each channel is provided via RFB0 to RFB15 pins.
