GENERAL D ESCRIP TIO N

T his device is a 7th order sigma-delta modulator that converts

the analog input signal into a high speed 1-bit data stream. T he

part operates from a +5 V supply and accepts a differential input

range of 0 V to +2.5 V or ±1.25 V centered about a common-

mode bias. T he analog input is continuously sampled by the

analog modulator, eliminating the need for external sample and

hold circuitry. T he input information is contained in the output

stream as a density of ones. T he original information can be

reconstructed with an appropriate digital filter.

T he part provides an accurate on-chip 2.5 V reference. A refer-

ence input/output function is provided to allow either the inter-

nal reference or an external system reference to be used as the

reference source for the part.

T he device is offered in a 28-lead T SSOP package and designed

to operate from –40°C to +85°C.
