Section 19 A/D Converter
19.1 Overview
The H8S/2633 Series incorporates a successive approximation type 10-bit A/D converter that
allows up to sixteen analog input channels to be selected.
19.1.1 Features
A/D converter features are listed below.
• 10-bit resolution
• Sixteen input channels
• Settable analog conversion voltage range
 Conversion of analog voltages with the reference voltage pin (Vref) as the analog reference
voltage
• High-speed conversion
 Minimum conversion time:
10.64 µs per channel (at 25 MHz operation)
• Choice of single mode or scan mode
 Single mode: Single-channel A/D conversion
 Scan mode: Continuous A/D conversion on 1 to 4 channels
• Four data registers
 Conversion results are held in a 16-bit data register for each channel
• Sample and hold function
• Three kinds of conversion start
 Choice of software or timer conversion start trigger (TPU or 8-bit timer), or ADTRG pin
• A/D conversion end interrupt generation
 A/D conversion end interrupt (ADI) request can be generated at the end of A/D conversion
• Module stop mode can be set
 As the initial setting, A/D converter operation is halted. Register access is enabled by
exiting module stop mode.
