DESCRIPTION
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
addition, the DAC7716 implements a
user-programmable system-level calibration function
to achieve ±0.0078 LSB zero error and ±0.0625 LSB
gain error.
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.
The DAC7716 is pin-compatible with the DAC8734
(16-bit) and the DAC8234 (14-bit).

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
