AD5516* 16-Channel, 12-Bit Voltage-Output DAC with 14-Bit Increment Mode *Protected by U.S. Patent No. FEATURES High Integration: 16-Channel DAC in 12 mm 12 mm CSPBGA 14-Bit Resolution via Increment/Decrement Mode Guaranteed Monotonic Low Power, SPI®, QSPI™, MICROWIRE™, and DSP Compatible 3-Wire Serial Interface Output Impedance 0.5 Output Voltage Range 2.5 V (AD5516-1) 5 V (AD5516-2) 10 V (AD5516-3) Asynchronous Reset Facility (via RESET Pin) Asynchronous Power-Down Facility (via PD Pin) Daisy-Chain Mode Temperature Range: –40 C to +85 C APPLICATIONS Level Setting Instrumentation Automatic Test Equipment Optical Networks Industrial Control Systems Data Acquisition Low Cost I/O FUNCTIONAL BLOCK DIAGRAM RFB0 RESET BUSY DACGND AGND DGND DCEN AD5516 DVCC AVCC VDD VSS VOUT0 RFB1 VOUT1 RFB14 VOUT14 RFB15 VOUT15 ROFFS RFB DAC VBIAS ROFFS RFB DAC ROFFS RFB DAC ROFFS RFB DAC REF_IN PD POWER-DOWN LOGIC SCLK DIN DOUT SYNC INTERFACE CONTROL LOGIC 7-BIT BUS ANALOG CALIBRATION LOOP MODE1 MODE2 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 inter- face. DAC selection is accomplished via address bits A3–A0. 14-bit resolution can be achieved by fine adjustment in Incre- ment/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 the 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. PRODUCT HIGHLIGHTS 1. Sixteen 12-bit DACs in one package, guaranteed monotonic. 2. Available in a 74-lead CSPBGA package with a body size of 12 mm 12 mm. 5,969,657. |
