GENERAL DESCRIPTION
The AD7834 and AD7835 contain four 14-bit DACs on one
monolithic chip. The AD7834 and AD7835 have output volt-
ages in the range of
±8.192 V with a maximum span of 14 V.
The AD7834 is a serial input device. Data is loaded in 16-bit
format from the external serial bus, MSB first after two leading
0s, into one of the input latches via DIN, SCLK and FSYNC.
The AD7834 has five dedicated package address pins, PA0–
PA4, that can be wired to AGND or VCC to permit up to 32
AD7834s to be individually addressed in a multipackage
application.
The AD7835 can accept either 14-bit parallel loading or
double-byte loading, where right-justified data is loaded in one
8-bit and one 6-bit byte. Data is loaded from the external bus
into one of the input latches under the control of the WR, CS,
BYSHF
and DAC channel address pins, A0–A2.
With either device, the LDAC signal can be used to update
either all four DAC outputs simultaneously or individually,
on reception of new data. In addition, for either device, the
asynchronous CLR input can be used to set all signal outputs,
VOUT1–VOUT4, to the user-defined voltage level on the Device
Sense Ground pin, DSG. On power-on, before the power sup-
plies have stabilized, internal circuitry holds the DAC output
voltage levels to within
±2 V of the DSG potential. As the sup-
plies stabilize, the DAC output levels move to the exact DSG
potential (assuming CLR is exercised).
The AD7834 is available in 28-pin 0.3" SO and 0.6" DIP pack-
ages, and the AD7835 is available in a 44-pin PQFP package
and a 44-pin PLCC package.
