AD5516

a 16-Channel, 12-Bit Voltage-Output DAC with 14-Bit Increment Mode AD5516* GENERAL DESCRIPTION The AD5516 is a 16-channel, 12-bit voltage-output DAC. The selected DAC register is written to via the 3-wire serial interface. DAC selection is accomplished via address bits A3–A0. 14-bit resolution can be achieved by fine adjustment in Increment/ Decrement Mode (Mode 2). The serial interface operates at clock rates up to 20 MHz and is compatible with standard SPI, MICROWIRE, and DSP interface standards. The output voltage range is fixed at ± 2.5 V (AD5516-1), ± 5 V (AD5516-2), and ± 10 V (AD5516-3). Access to the feedback resistor in each channel is provided via RFB0 to RFB15 pins. The device is operated with AVCC = 5 V ± 5%, DVCC = 2.7 V to 5.25 V, VSS = –4.75 V to –12 V, and VDD = +4.75 V to +12 V and requires a stable 3 V reference on REF_IN.
