14.1
The SH7050 series includes a 10-bit successive-approximation A/D converter., with software
selection of up to 16 analog input channels.
The A/D converter is composed of two independent modules, A/D0 and A/D1. A/D0 comprises
three groups, while A/D1 comprises a single group.
14.1.1
The features of the A/D converter are summarized below.
Module
A/D0
A/D1
10-bit resolution
16 input channels (A/D0: 12 channels, A/D1: 4 channels)
High-speed conversion
Conversion time: minimum 6.7 µs per channel (when = 20 MHz)
Two conversion modes
Sixteen 10-bit A/D data registers
A/D conversion results are transferred for storage into data registers corresponding to the
channels.
Two sample-and-hold circuits
A sample-and-hold circuit is built into each A/D converter module (AD/0 and AD/1),
simplifying the configuration of external analog input circuitry.
Single mode: A/D conversion on one channel
Scan mode:
Continuous conversion on 1 to 12 channels (A/D0)
Continuous conversion on 1 to 4 channels (A/D1)
