The LTC
®
1096/LTC1096L/LTC1098/LTC1098L are
micropower, 8-bit A/D converters that draw only 80µ A of
supply current when converting. They automatically power
down to 1nA typical supply current whenever they are not
performing conversions. They are packaged in 8-pin SO
packages and have both 3V (L) and 5V versions. These
8-bit, switched-capacitor, successive approximation ADCs
include sample-and-hold. The LTC1096/LTC1096L have a
single differential analog input. The LTC1098/LTC1098L
offer a software selectable 2-channel MUX.
On-chip serial ports allow efficient data transfer to a wide
range of microprocessors and microcontrollers over three
wires. This, coupled with micropower consumption, makes
remote location possible and facilitates transmitting data
through isolation barriers.
These circuits can be used in ratiometric applications or
with an external reference. The high impedance analog
inputs and the ability to operate with reduced spans
(below 1V full scale) allow direct connection to sensors
and transducers in many applications, eliminating the
need for gain stages.

The ● denotes specifications which apply over the 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: For the 8-lead PDIP, consult the factory.
Note 4: Linearity error is specified between the actual and 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. 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 5V input voltage range
will therefore require a minimum supply voltage of 4.950V over initial
tolerance, temperature variations and loading. For 5.5V < V
CC
≤ 9V,
reference and analog input range cannot exceed 5.55V. If reference and
analog input range are greater than 5.55V, the output code will not be
guaranteed to be correct.
Note 7: The supply voltage range for the LTC1096L/LTC1098L is from
2.65V to 4V. The supply voltage range for the LTC1096 is from 3V to 9V,
but the supply voltage range for the LTC1098 is only from 3V to 6V.
Note 8: Channel leakage current is measured after the channel selection.
Note 9: These specifications are either correlated from 5V specifications or
guaranteed by design.

* Maximum CLK frequency represents the clock frequency at which a 0.1LSB shift in the error at any code
transition from its 0.75MHz value is first detected.
†
As the CLK frequency is decreased from 500kHz, minimum CLK frequency (∆error ≤ 0.1LSB) represents
the frequency at which a 0.1LSB shift in any code transition from its 500kHz value is first detected.
