DESCRIPTION
The DAC7715 is a quad, serial input, 12-bit, voltage
output Digital-to-Analog Converter (DAC) with
guaranteed 12-bit monotonic performance over the
–40°C to +85°C temperature range. An asynchronous
reset clears all registers to either mid-scale (800H) or
zero-scale (000H), selectable via the RESETSEL pin.
The individual DAC inputs are double buffered to
allow for simultaneous update of all DAC outputs.
The device can be powered from a single +15V supply
or from dual +15V and –15V supplies.
Low power and small size makes the DAC7715 ideal
for automatic test equipment, DAC-per-pin program-
mers, data acquisition systems, and closed-loop servo-
control. The device is available in a SO-16 package
and is guaranteed over the –40°C to +85°C tempera-
ture range.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDECindustry standard classifications, and peak solder
temperature.
