2.4.2 ADQ32 Analog-to-Digital Converter

The ADQ32 is an analog-to-digital converter with DMA capability.

Functional Information

Input channels 32 single-ended analog input channels or 16

differential analog input channels; single-ended or

differential is programmable

Programmable gain 1, 2, 4, or 8; selectable per channel

A/D output

Resolution 12-bit output data resolution

Data notation Straight binary (unipolar), two’s complement

(bipolar)

A/D conversions Can be started by a program, a real-time clock, or

an external trigger

A/D results Can be received by a programmed I/O transfer or

by servicing an interrupt request

Interrupts Can be enabled and automatically set

Common mode rejection ratio 55 dB at maximum range
