TEMPERATURE MEASUREMENT
The DS620 measures temperature using a bandgap-based temperature sensor. A delta-sigma, analog-to-digital
converter (ADC) converts measured temperature to a 10-, 11-, 12-, or 13-bit (user-selectable) digital value that is
calibrated in 癈; for 癋 applications, a lookup table or conversion routine must be used. Throughout this data sheet,
the term conversion is used to refer to the entire temperature measurement and ADC sequence.
The DS620 can be configured to power up either automatically converting temperature or in a low-power standby
state. The preferred power-up mode can be set using the AUTOC bit in the configuration register as explained in
the Configuration Register section of this data sheet.
The DS620 can be programmed to perform continuous consecutive conversions (continuous conversion mode) or
to perform single conversions on command (one-shot mode). The conversion mode is programmed through the
1SHOT bit in the configuration register as explained in the Configuration Register section of this data sheet. In
continuous conversion mode, conversions are performed after a Start Convert command is issued (or upon power-
up if the AUTOC bit in the configuration register is set to 1) until a Stop Convert command is issued, at which time
the device goes into a low-power standby state. Continuous conversions can be restarted at any time using the
Start Convert command. In one-shot mode, the DS620 performs a single temperature conversion either at power-
up (if AUTOC = 1) or when a Start Convert command is issued (if AUTOC = 0). When the conversion is complete,
