This document introduces the features of the ADT7516/ADT7517/ADT7519 products, including four 12-bit DACs, 10-bit temperature converter, 10-bit 4-channel ADC, etc.
The ADT7516, ADT7517, and ADT7519 are temperature‑sensor ICs that combine a 10‑bit temperature‑to‑digital converter, a 10‑bit 4‑channel ADC, and a quad DAC (12‑/10‑/8‑bit respectively) in a 16‑lead QSOP package. They operate from a single 2.7 V to 5.5 V supply and offer both 4‑wire SPI‑compatible and 2‑wire SMBus/I²C serial interfaces.
These devices are suited for portable battery‑powered instruments, personal computers, smart battery chargers, telecommunications, domestic appliances, and process‑control applications. The handbook includes detailed specifications, timing diagrams, functional block diagrams, and ordering information.
| Supply voltage range | 2.7 V to 5.5 V |
|---|---|
| Temperature range | –40 °C to +120 °C |
| Power‑down current | <10 pA |
| DAC resolution (ADT7516) | 12 bits |
| DAC resolution (ADT7517) | 10 bits |
| DAC resolution (ADT7519) | 8 bits |
| ADC resolution | 10 bits |
They support a 4‑wire SPI‑compatible interface (including QSPI, MICROWIRE, and DSP) and a 2‑wire SMBus/I²C interface.
The DAC output can swing from 0 V to 2 V.
Typical settling time is about 7 µs.
The device draws less than 10 pA in power‑down mode.
