INTERFACE
The SDM components are complete, pin-compatible,
dataacquisitionsystemshousedinahermeticallysealed
1"-square leadless chip carrier or a 1.1"-square pin grid
array. The small package outlines and low power con-
sumption provide an ideal data acquisition solution
when space is at a premium.
● GUARANTEED NO MISSING CODES OVER

● SURFACE-MOUNT OR PIN GRID ARRAY
PACKAGE OPTIONS
● HIGH RELIABILITY SCREENED VERSIONS
AVAILABLE
The devices comprise of an input multiplexer, instru-
mentation amplifier with selectable gains, sample/hold
amplifierandA/Dconverterwithmicroprocessorinter-
face and three-state buffers.
● FULL SPECIFICATION OVER THREE
TEMPERATURE RANGES:
0 to +70°C, –25 to +85°C, –55 to +125°C
● EVERY UNIT SUPPLIED WITH
The SDM family will accept unipolar or bipolar voltage
inputs in the range 0 to +10V, ±5V and ±10V. For low-
level signals, jumper-selectable gains of 10 or 100 can
be applied. The number of input channels can be ex-
panded by the addition of multiplexers. System integra-
tion is simplified by the microprocessor interface and
the facility of the sample/hold amplifier being con-
trolled directly by the A/D converter.
