The TPMC500 is a PCI Mezzanine Card compatible

module providing 32 galvanically isolated multiplexed

16 bit ADC channels.. The data acquisition and conversion

time is mode-dependent: Maximum 10μs without channel /

gain change, maximum 12.5μs with channel / gain

change.

The ADC input channels can be software configured to

operate in single-ended mode (up to 32 input channels) or

differential mode (up to 16 input channels). Mixed mode

operation is also possible.

The ADC multiplexer is overvoltage protected up to

70Vpp. A programmable gain amplifier allows gains of 1,

2, 5, 10 (TPMC500-10R, -12R, -20R and –22R) or 1, 2, 4,

8 (TPMC500-11R, -13R, -21R and –23R). For a gain of 1,

the full-scale input voltage range is +/-10V for the

TPMC500-10R, -11R, -20R, -21R and 0V to 10V for the

TPMC500-12R, -13R, -22R, -23R.

Additionally the TPMC500 provides a sequencer to control

the analog inputs without wasting CPU time.

Each channel can be independently enabled and

configured by a sequencer instruction RAM. After the last

instruction of a programmed sequence has been

completed the ADC data of all channels enabled for the

sequence are stored in the data RAM.

The repeat frequency of the sequencer can be

programmed by using the sequence timer. The sequence

timer is programmable from 100μs to 6.5535sec in steps

of 100μs. Whenever the timer reaches the programmed

value the sequencer starts a new sequence. A special

function is the sequencer continuous mode. It is activated,

if the sequence timer register is set to 0. In this mode the

sequencer will start again with the first instruction of the

sequence as soon as the last instruction of the previous

sequence has been completed.

Each TPMC500 is factory calibrated. The calibration data

is stored in an EEPROM unique to each TPMC500.

Software support (TPMC500-SW-xx) is available for

different operating systems.
