DESCRIPTION

The HS9410 Series is a complete 8-channel, micro-

processor-compatible, 12-bit data acquisition system

with all the interface logic to connect directly to

8- or 16-bit microprocessor buses. It is contained in

a 28-pin DIP and includes an 8-channel multiplexer,

a sample-and-hold amplifier, and a 12-bit A/D

converter along with the control logic needed to

perform a complete data acquisition function. System

throughput rate is 25kHz for full rated accuracy.

The analog-to-digital converter section contains

the HS574 12-bit A DC. The HS9410 Series is offered

in a hermetically sealed package for use over a

wide temperature range and for M IL-STD-883

requirements.

The HS9410 Series operates from ±15V * and +5V

with a total power consumption of 400mW . To take

advantage of the 28-pin package, the user must

specify an input range of 0 to +10V , ±5V or ±10V

when ordering. Four basic product grades are

available; J and K models are specified over a

temperature range of 0ºC to +70ºC while the S

and T models are specified over an extended

temperature range of –55ºC to +125ºC. Full

screening to M IL-STD-883C and processing in ac-

cordance with M ethod 5008.1 is available with

models specified as “ B.”

* ±12V operation possible; consult factory for further information.
