The SDM components are complete, pin-compatible,
data acquisition systems housed in a hermetically sealed
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.
The devices comprise of an input multiplexer, instru-
mentation amplifier with selectable gains, sample/hold
amplifier and A/D converter with microprocessor inter-
face and three-state buffers.
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.

NOTES: (1) Measured at the same and hold output. (2) Measured with all input channels grounded. (3) The range of voltage on any input with respect to common over
which accuracy and leakage current is guaranteed. (4) Applicable over full operating temperature range. NO MISSING CODES GUARANTEED OVER TEMPERATURE
RANGE. (5) Adjustable to zero using external potentiometer or select-on-test resistor. (6) Specifications are at +25°C and measured at 50% level of transition. (7) When
using TTL drivers a 1kpull-up resistor should be used. (8) Muxes operate in a break-before-make manner.
