Micropower Sampling
8-Bit Serial I/O A/D Converters
D
The LTC
1096/LTC1096L/LTC1098/LTC1098L are
micropower, 8-bit A/D converters that draw only 80
μ
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.
