LTC2480
2480fd
Input signals applied to IN+ and IN– pins may extend by
300mV below ground and above VCC. In order to limit any
fault current, resistors of up to 5k may be added in series
withtheIN+andIN–pinswithoutaffectingtheperformance
of the devices. The effect of the series resistance on the
converter accuracy can be evaluated from the curves
presentedintheInputCurrent/ReferenceCurrentsections.
In addition, series resistors will introduce a temperature
dependent offset error due to the input leakage current.
A 1nA input leakage current will develop a 1ppm offset
error on a 5k resistor if VREF = 5V. This error has a very
strong temperature dependency.
Serial Interface Timing Modes
The LTC2480’s 4-wire interface is SPI and MICROWIRE
compatible. This interface offers several flexible modes of
operation. These include internal/external serial clock,
3-or4-wireI/O,singlecycleorcontinuousconversion.The
following sections describe each of these serial interface
timing modes in detail. In all these cases, the converter
can use the internal oscillator (fO = LOW or fO = HIGH)
or an external oscillator connected to the fO pin. Refer to
Table 6 for a summary.
External Serial Clock, Single Cycle Operation
(SPI/MICROWIRE Compatible)
This timing mode uses an external serial clock to shift
out the conversion result and a CS signal to monitor and
control the state of the conversion cycle, see Figure 5.
The serial clock mode is selected on the falling edge
of CS. To select the external serial clock mode, the
serial clock pin (SCK) must be LOW during each CS
falling edge.
