CONVERTER OPERATION
Converter Operation Cycle
The LTC2439-1 is a multichannel, low power, delta-sigma
analog-to-digital converter with an easy-to-use 4-wire se-
rial interface (see Figure 1). Its operation is made up of three
states. The converter operating cycle begins with the con-
version, followed by the low power sleep state and ends with
the data input/output (see Figure 2). The 4-wire interface
consists of serial data input (SDI), serial data output (SDO),
serial clock (SCK) and chip select (CS).
Initially, the LTC2439-1 performs a conversion. Once the
conversion is complete, the device enters the sleep state.
The part remains in the sleep state as long as CS is HIGH.
While in the sleep state, power consumption is reduced by
nearly two orders of magnitude. The conversion result is
held indefinitely in a static shift register while the converter
is in the sleep state.
