Section 15 High Speed A/D Converter (Excluding A Mask)

15.1 Overview

The high speed A/D converter has 10-bit resolution, and can select from a maximum of eight

channels of analog inputs.

15.1.1 Features

The high speed A/D converter has the following features:

â¢ 10-bit resolution

â¢ Eight input channels

â¢ Analog conversion voltage range setting is selectable

ï£§ Using the reference voltage pin (AVref) as an analog standard voltage (Vref), conversion of

analog input from 0 to Vref (only with SH7043).

â¢ High-speed conversion

ï£§ Minimum conversion time: 2.9 Âµs per channel (for 28-MHz operation)

ï£§ 1.4 Âµs per channel during continuous conversion

â¢ Multiple conversion modes

ï£§ Select mode/group mode

ï£§ Single mode/scan mode

ï£§ Buffered operation possible

ï£§ 2 channel simultaneous sampling possible

â¢ Three types of conversion start

ï£§ Software, timer conversion start trigger (MTU), or ADTRG pin can be selected.

â¢ Eight data registers

ï£§ Conversion results stored in 16-bit data registers corresponding to each channel.

â¢ Sample and hold function

â¢ A/D conversion end interrupt generation

ï£§ An A/D conversion end interrupt (ADI) request can be generated on completion of A/D

conversions
