8 Channel, 12 Bit D ata Acquisition
System W ith µP Interface
FEATURES
Complete 8 channel, 12-bit data acquisition
system with M UX, S/H, REF, clock and three-
state outputs
Full 8- or 16-bit microprocessor bus interface
Guaranteed linearity over temperature
High throughput rate: 25kHz
Hermetic 28-pin
Low Power: 400mW
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.
H S9410 Series
D ata Converter Line
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.

NOTES
1 For J and K models, positive analog input voltage should not exceed V CC –4 volts. Exceeding \/CC –4 volts can cause an OFF channel to be turned ON. Negative
input voltages and input voltages for S and T models may go to supply voltages. Input voliages exceeding these values will not result in permanent damage as long
as the absolute maximum ratings are not exceeded. 2. 1 K pullup to + 5V recommended for M A 0 -M A 2 when driven by TTL 3.M aximum change over rated supply
voltage. 4. Externally adjustable to zero. See A pplications Information.
