GENERATION

The AD7741/AD7742 are a new generation of synchronous

voltage-to-frequency converters (VFCs). The AD7741 is a

single-channel version in an 8-lead package (SOIC/DIP) and the

AD7742 is a multichannel version in a 16-lead package (SOIC/

DIP). No user trimming is required to achieve the specified

performance.

CLKIN CLKOUT REFIN

REFOUT

The AD7741 has a single buffered input whereas the AD7742

has four buffered inputs that may be configured as two fully-

differential inputs or three pseudo-differential inputs. Both parts

include an on-chip +2.5 V bandgap reference that provides the

user with the option of using this internal reference or an exter-

nal reference.

The AD7741 has a single-ended voltage input range from 0 V

to REFIN. The AD7742 has a differential voltage input range

from –V_REFto +V_REF. Both parts operate from a single +5 V

supply consuming typically 6 mA, and also contain a power-

down feature that reduces the current consumption to less than

35 µA.
