ADT7516/ADT7517/ADT7519 is a SPI/I2C compatible, temperature sensor, 4-channel ADC and quad voltage output DAC
The ADT7516, ADT7517 and ADT7519 are Analog Devices’ SPI/I²C‑compatible temperature‑sensor devices that integrate a temperature‑to‑digital converter, a 4‑channel ADC and a quad‑output DAC in a 16‑lead QSOP package.
The datasheet provides detailed specifications, pin descriptions, functional block diagrams, timing diagrams for SPI and I²C, absolute‑maximum ratings, recommended operating conditions, register maps and interface guidelines.
| Temperature range | –40 °C to +120 °C |
|---|---|
| Supply voltage range | 2.7 V to 5.5 V |
