ADT7516/ADT7517/ADT7519 is a SPI-/I2C-compatible, temperature sensor, 4-channel ADC and quad voltage output integrated circuit manufactured by Analog Devices.
The ADT7516/ADT7517/ADT7519 family combines a temperature sensor, a 10‑bit 4‑channel ADC and a quad DAC (12‑bit, 10‑bit or 8‑bit depending on the part) in a 16‑lead QSOP package. The devices operate from a single 2.7 V to 5.5 V supply and support SPI, I2C, QSPI, MICROWIRE, DSP‑compatible and SMBus interfaces.
Key features include buffered voltage outputs, monotonic DAC operation, low power‑down current (<10 µA), and programmable over‑/under‑limit interrupt pins. The data sheet provides detailed specifications, pin descriptions, timing diagrams, and absolute maximum ratings for design engineers.
