Preliminary Technical Data
AD7741 PIN FUNCTION DESCRIPTION
Pin
No.
Pin
Mnemonic
Description
V
DD
GND
Positive supply voltage, +5 V ± 5%.
Analog Ground. Ground reference for Programmable Gain Amplifier, Voltage-to-Frequency Con
verter and Bandgap Reference.
CLKOUT
External Clock Output. When the master clock for the device is a crystal, the crystal is connected
between CLKIN and CLKOUT. When an external clock is applied to CLKIN, CLKOUT pro-
vides an inverted clock signal. This clock must be buffered before being used to provide a clock
source for a microprocessor, ADC or other system components.
External Clock Input. The master clock for the device can be provided in the form of a crystal or
an external clock. A crystal can be tied across the CLKIN, CLKOUT pins. Alternatively, the
CLKIN pin can be driven with a CMOS-compatible clock and CLKOUT left unconnected. The
frequency on CLK IN can be as high as 5MHz.
CLKIN
REF IN
Voltage Reference Input. A precision reference (e.g. REF192) is applied to this pin.
V
IN
Analog Input Channel. The analog input range is from 0V to REF IN. An input signal equal to 0V
results in an output frequency of F
min (5% of F
CLOCK
) and an input of REF IN results in an
output frequency of F
OUT
max (45% of F
CLOCK
).
F
OUT
Frequency Output.
