APPLICATIONS INFORMATION
CONVERTER OPERATION
Converter Operation Cycle
The LTC2482 is a low power, delta-sigma analog-to-digital
converter with an easy-to-use 3-wire serial interface and
automatic differential input current cancellation. Its opera-
tion is made up of three states. The converter operating
cycle begins with the conversion, followed by the low power
sleep state and ends with the data output (see Figure 1).
The 3-wire interface consists of serial data output (SDO),
serial clock (SCK) and chip select (CS).
Initially, the LTC2482 performs a conversion. Once the
conversion is complete, the device enters the sleep state.
While in this sleep state, power consumption is reduced
