GENERAL DESCRIPTION
This device consists of two seventh order sigma-delta modula-
tors. Each modulator converts its analog input signal into a high
speed 1-bit data stream. The part operates from a 5 V power
supply and accepts a differential input range of 0 V to +2.5 V or
±1.25 V centered about a common-mode bias. The analog inputs
are continuously sampled by the analog modulators, eliminating
the need for external sample-and-hold circuitry. The input
information is contained in the output stream as a density of
ones. The original information can be digitally reconstructed
with an appropriate digital filter.
The part provides an accurate on-chip 2.5 V reference for each
modulator. A reference input/output function is provided to
allow either the internal reference or an external system refer-
ence to be used as the reference source for the modulator.
The device is offered in a 48-lead LQFP package and designed
to operate from –40
°C to +85°C.
