TIP845

48 Channel of 14 bit A/D Conversion

Application Information

The TIP845 is an IndustryPack® compatible module

providing 48 single-ended or 24 differential ADC input

channels. The data acquisition and conversion time is up

to 2.5µs without channel / gain change and up to 10.5µs

with channel / gain change. The resolution is 14 bit.

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.

Additionally the TIP845 provides a sequencer to control

the analog inputs without wasting CPU time. Each of the

A/D

channels

can

be

independently

enabled

and

configured by a sequencer instruction RAM. After the last

instruction of a programmed sequence has completed, the

ADC data of all enabled channels 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 6.5535s in steps of

100µs. The sequencer starts a new sequence whenever

the timer reaches the programmed value.

A special function is the sequencer continuous mode. It is

activated by setting the sequence timer register 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.

An interrupt can be generated at end-of-settling, end-of-

conversion or end-of-sequencer cycle supporting an 8 bit

vector.

Each

TIP845

is

factory

calibrated.

The

calibration

information is stored in the Identification-PROM unique to

each IP.

Software support (TIP830-SW-xx) is available for different

operating systems.
