The AD7582 is a medium speed, 4-channel 12-bit CMOS A/D converter that uses the successive approximation technique. It features an autozero cycle at the start of each conversion to achieve very low system offset voltages, typically less than 100uV. The device is designed for easy microprocessor interface using standard control signals: CS (decoded device address), RD (READ), and WR (WRITE).
| Total Unadjusted Error | +1 LSB max |
|---|---|
| Conversion Time | 100us per channel |
| Number of Channels | 4 |
| Operating Temperature Range (K/B Version) | -40°C to +85°C |
The device has four high impedance input channels.
The autozero cycle results in very low system offset voltages, typically less than 100uV.
