Converter Operation Cycle
The LTC2482 is a low power, delta-sigma analog-to-digital SLEEP 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 FALSE CS = LOW cycle begins with the conversion, followed by the low power AND sleep state and ends with the data output (see Figure 1). SCK The 3-wire interface consists of serial data output (SDO), TRUE serial clock (SCK) and chip select (CS). DATA OUTPUT Initially, the LTC2482 performs a conversion. Once the 2482 F01 conversion is complete, the device enters the sleep state. While in this sleep state, power consumption is reduced
