Function
Reset ADC: LOW = Enables the converter. HIGH = Abort conversion (if any).
Power down: LOW = Enables the converter . HIGH = Powers down the converter. Power
consumption is reduced to a minimum after the current conversion.
Internal reference buffer power down: LOW = Enable on chip buffer. HIGH = Power down
internal buffer.
Internal reference power down: LOW = Enable on chip reference. HIGH = Power down internal
reference. Note that when using the on chip reference, the buffer also needs to be enabled
(PDREF = PDBUF = HIGH).
Analog ground close to SIG+.
Digital ground near SJ2.
Analog ground close to REF.
Analog ground close to SIG-.
Description
BUSY signal.
Same as S16, position 5
Analog +input.
Reference input. Output for devices with on-chip reference.
CNVST signal.
CS , chip select signal.
RD , read signal.
Digital output supply.
Digital core supply.
Analog supply.
Analog –input for differential parts.
Buffered serial clock.
Buffered serial sync.
Buffered serial data.
TEMP, for ADC with internal reference. Outputs temperature dependant voltage (approx.
300mV with T
For ADCs with internal reference, REFBUFIN can be used to connect external reference into
the reference buffer input when PDBUF = LOW and PDREF = HIGH. With the internal
reference (and buffer) enabled, this pin will produce the intenal bandgap refrence voltage.
Internal reference bandgap supply. Connected to AVDD via s19.
Direct ADC serial data.
Direct ADC serial clock.
Direct ADC serial SYNC.
Direct ADC serial read error.
