General Description
The TC530/TC534 are serial analog data acquisition
subsystems ideal for high precision measurements (up
to 17-bits plus sign). The TC534 consists of a dual
slope integrating
supply generator and 3 wire serial interface port. The
TC530 is identical to the TC534, but adds a four
channel
converter operating parameters (Auto Zero and Inte-
gration time) are programmable, allowing the user to
trade conversion time for resolution.
Data conversion is initiated when the RESET input is
brought low. After conversion, data is loaded into the
output shift register and EOC is asserted, indicating
new data is available. The converted data (plus Over-
range and polarity bits) is held in the output shift
register until read by the processor or until the next
conversion is completed, allowing the user to access
data at any time.
The TC530/TC534 timebase can be derived from an
external crystal of 2MHz (max) or from an external fre-
quency source. The TC530/TC534 requires a single 5V
power supply and features a -5V, 10mA output which
can be used to supply negative bias to other
components in the system.
