LTC1096L
CS/SHDN (Pin 1):
Chip Select Input. A logic low on this
input enables the LTC1096L. A logic high on this input
disables the LTC1096L and disconnects the power to the
LTC1096L.
IN
+
(Pin 2):
Analog Input. This input must be free of noise
with respect to GND.
IN
–
(Pin 3):
Analog Input. This input must be free of noise
with respect to GND.
GND (Pin 4):
Analog Ground. GND should be tied directly
to an analog ground plane.
V
REF
(Pin 5):
Reference Input. The reference input defines
the span of the A/D converter and must be kept free of
noise with respect to GND.
D
OUT
(Pin 6):
Digital Data Output. The A/D conversion
result is shifted out of this output.
CLK (Pin 7):
Shift Clock. This clock synchronizes the serial
data transfer.
V
CC
(Pin 8):
Power Supply Voltage. This pin provides
power to the A/D converter. It must be free of noise and
ripple by bypassing directly to the analog ground plane.
LTC1098L
CS/SHDN (Pin 1):
Chip Select Input. A logic low on this
input enables the LTC1098L. A logic high on this input
disables the LTC1098L and disconnects the power to the
LTC1098L.
CHO (Pin 2):
Analog Input. This input must be free of noise
with respect to GND.
The
G
denotes specifications which apply over the full operating
temperature range.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
All voltage values are with respect to GND.
Note 3:
This device is specified at 2.65V. Consult factory for 5V specified
devices.
Note 4:
Linearity error is specified between the actual end points of the
A/D transfer curve.
Note 5:
Total unadjusted error includes offset, full scale, linearity,
multiplexer and hold step errors.
Note 6:
Two on-chip diodes are tied to each reference and analog input
which will conduct for reference or analog input voltages one diode drop
below GND or one diode drop above V
CC
. This spec allows 50mV forward
bias of either diode for 2.65V
≤
V
CC
≤
3.6V. This means that as long as the
reference or analog input does not exceed the supply voltage by more than
50mV, the output code will be correct. To achieve an absolute 0V to 3V
input voltage range will therefore require a minimum supply voltage of
2.950V over initial tolerance, temperature variations and loading.
Note 7:
Channel leakage current is measured after the channel selection.
