Multifunction I/O 16-bit A/D, 16-bit D/A, TTL I/O, Counter PMC Module
|
The TPMC851 combines 32 single ended / 16 differential channels of 16 bit multiplexed analog input, 8 channels of 16 bit analog output, 16 digital I/O lines and a 32 bit multi-purpose counter on a standard single-width PMC module.
A 16 bit ADC converts 32 single-ended or 16 differential multiplexed ADC input channels. The data acquisition and conversion time is up to 1.25 µs without channel/gain change and up to 17.25 µs with channel/gain change. The input multiplexer of the A/D circuit offers analog overvoltage protection of up to 70Vpp. A programmable gain amplifier allows gains of 1, 2, 4 or 8 resulting in input voltage ranges of ±10V, ±5V, ±2.5V or ±1.25V.
The ADC part of the TPMC851 can operate in Manual Mode or Sequencer Mode:
Manual Mode
In Manual Mode the multiplexer, programmable gain amplifier and the converter are fully controlled by the user. A conversion for a selected channel / gain can be started automatically after the settling time has elapsed, or manually by the user.
Sequencer Mode
In Sequencer Mode each of the A/D channels can be independently enabled and configured for the sequencer. The sequencer can run continuously, at specific time intervals, or it may be triggered by an external event. Conversion data is stored in a data RAM.
The 8 analog output channels are realized by eight 16 bit digital to analog converters (DACs). The conversion time is 10 µs. An operational amplifier drives the full-scale range of ±10V and is capable to drive high capacitive loads. Similar to the analog inputs a sequencer can control the analog outputs.
Following operation modes are available:
Immediate Update: Updates the DAC output immediately when new data is written to the DAC channel.
Simultaneous Update: DAC data is buffered and all DAC outputs are updated simultaneously on a trigger event:
- Manual Update: Updates all DAC outputs on a manual event (register write)
- Trigger Update: Updates all DAC outputs on a external event
- Sequencer Update: Updates all DAC outputs after the sequencer timer has elapsed
