FEATURES  
DESCRIPTION

•
Bipolar Output: Up to ±16V  
Unipolar Output: 0V to +20V  
12-Bit Monotonic  
The DAC7716 is a high-accuracy, quad-channel,  
12-bit digital-to-analog converter (DAC) that operates  
from supply voltages of ±5V to ±18V in bipolar output  
mode, and from ±5V to +24V/–12V in unipolar mode.  
With a 5V reference, the DAC7716 can be configured  
to output ±10V, ±5V, 0V to 20V, or 0V to 10V. The  
DAC7716 provides 12-bit monotonicity, excellent  
integral nonlinearity (INL) error of ±1 LSB, low glitch,  
and low noise over the operating temperature range  
of –40°C to +105°C. This device is trimmed in  
production for very low zero and gain errors. In

to achieve ±0.0078 LSB zero error and ±0.0625 LSB  
gain error.  
Settling Time: 6µs  
Configurable Gain: x2/x4  
Analog Output Monitor  
The DAC7716 has integrated reference buffers and  
output buffers. It features a standard high-speed  
1.8V, 3V, or 5V serial peripheral interface (SPI) that  
operates at clock rates of up to 50MHz to  
communicate with a DSP or microprocessor. The four  
DAC channels and the auxiliary registers are  
addressed with four address bits. The device features  
double-buffered interface logic for simultaneous  
updates of all DACs. An asynchronous load input  
(LDAC) transfers data from the input data register to  
the DAC latch, and the contents of the DAC latch set  
the output voltage. The asynchronous RST input sets  
the output of all four DACs to 0V. The VMON pin is an  
analog monitor output that multiplexes the individual  
DAC outputs or the AIN pin.
