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:

• 10-bit resolution

• Eight input channels

• Analog conversion voltage range setting is selectable

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

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

• High-speed conversion

 Minimum conversion time: 2.9 µs per channel (for 28-MHz operation)

 1.4 µs per channel during continuous conversion

• Multiple conversion modes

 Select mode/group mode

 Single mode/scan mode

 Buffered operation possible

 2 channel simultaneous sampling possible

• Three types of conversion start

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

• Eight data registers

 Conversion results stored in 16-bit data registers corresponding to each channel.

• Sample and hold function

• A/D conversion end interrupt generation

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

conversions
