2.4.3 ADV11–S Analog-to-Digital Converter

The ADV11–S is an analog-to-digital converter with DMA capability. The

ADV11–S is functionally equivalent to an ADV11–D.

Functional Information

Input channels 16 single-ended analog input channels or 8

differential analog input channels; SE/DI input is

jumper-selectable.

Programmable gain 1, 2, 4, or 8

A/D output

Resolution 12-bit output data resolution

Data notation Binary, offset binary, or two’s complement

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 by A/D

DONE and/or ERROR bits

Common mode rejection ratio (gain=1) 80 dB at maximum range
