16-Channel, 12-Bit Voltage-Output DAC with 14-Bit Increment Mode * AD5516 FEATURES GENERAL DESCRIPTION High Integration: The AD5516 is a 16-channel, 12-bit voltage-output DAC. The 16-Channel DAC in 12 mm 12 mm CSPBGA selected DAC register is written to via the 3-wire serial inter- 14-Bit Resolution via Increment/Decrement Mode face. DAC selection is accomplished via address bits A3A0. Guaranteed Monotonic 14-bit resolution can be achieved by fine adjustment in Incre- Low Power, SPI , QSPI, MICROWIRE, and ment/Decrement Mode (Mode 2). The serial interface operates DSP Compatible at clock rates up to 20 MHz and is compatible with standard 3-Wire Serial Interface SPI, MICROWIRE, and DSP interface standards. The output Output Impedance 0.5 voltage range is fixed at 2.5 V (AD5516-1), 5 V (AD5516-2), Output Voltage Range and 10 V (AD5516-3). Access to the feedback resistor in each 2.5 V (AD5516-1) channel is provided via the R 0 to R 15 pins. FB FB 5 V (AD5516-2) The device is operated with AV = 5 V 5%, DV = 2.7 V CC CC 10 V (AD5516-3) to 5.25 V, V = 4.75 V to 12 V, and V = +4.75 V to +12 V, SS DD Asynchronous Reset Facility (via RESET Pin) and requires a stable 3 V reference on REF IN. Asynchronous Power-Down Facility (via PD Pin) Daisy-Chain Mode PRODUCT HIGHLIGHTS Temperature Range: 40 C to +85 C 1. Sixteen 12-bit DACs in one package, guaranteed monotonic. APPLICATIONS 2. Available in a 74-lead CSPBGA package with a body size of Level Setting 12 mm 12 mm.
