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 LFBGA

 

selected DAC register is written to via the 3-wire serial interface.

 

14-Bit Resolution via Increment/Decrement Mode

DAC selection is accomplished via address bits A3–A0. 14-bit

 

Guaranteed Monotonic

 

resolution can be achieved by fine adjustment in Increment/

 

Low Power, SPITM, QSPITM, MICROWIRETM, and DSP-

Decrement Mode (Mode 2). The serial interface operates at

 

Compatible

 

clock rates up to 20 MHz and is compatible with standard SPI,

 

3-Wire Serial Interface

 

MICROWIRE, and DSP interface standards. The output volt-

 

Output Impedance 0.5

 

age 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 RFB0 to RFB15 pins.

 

5 V (AD5516-2)

 

The device is operated with AVCC = 5 V ± 5%, DVCC = 2.7 V to

 

10 V (AD5516-3)

 

5.25 V, VSS = –4.75 V to –12 V, and VDD = +4.75 V to +12 V

 

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

NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

2Transient currents of up to 100 mA will not cause SCR latch-up.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD5516 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
