AD1879JD
Analog-to-
Digital Converter

The AD1879 consists of two integrated circuits in a single ceramic 28-pin DIP package. The modulators and reference are fabricated in a BiCMOS process; the decimator and output port, in a 1.0 µm CMOS process. Separating these functionreduces digital crosstalk to the analog circuitry. Analog and digital supply connections are separated to further isolate the analog circuitry from the digital supplies.
The AD1879 operates from ±5 V power supplies over the temperature range of –25°C to +70°C.

In their original tubes of 13pcs.
