ADT7516 General Description
The ADT7516/ADT7517/ADT75191 combine a 10-bit temp-erature-to-digital converter, a 10-bit 4-channel ADC, and a quad 12-/10-/8-bit DAC, respectively, in a 16-lead QSOP package. The parts also include a band gap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C.
The ADT7516/ADT7517/ ADT7519 operate from a single 2.7 V to 5.5 V supply. The input voltage range on the ADC channels is 0 V to 2.28 V, and the input bandwidth is dc. The reference for the ADC channels is derived internally. The output voltage of the DAC ranges from 0 V to VDD, with an output voltage settling time of 7 ms typical.
The ADT7516/ADT7517/ADT7519 provide two serial interface options: a 4-wire serial interface that is compatible with SPI, QSPI, MICROWIRE, and DSP interface standards, and a 2-wire SMBus/I2C interface. They feature a standby mode that is controlled through the serial interface.
The reference for the four DACs is derived either internally or from a reference pin. The outputs of all DACs may be updated simultaneously using the software LDAC function or the external LDAC pin. The ADT7516/ADT7517/ADT7519 incorporate a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write takes place.
The ADT7516/ADT7517/ADT7519's wide supply voltage range, low supply current, and SPI/I2C compatible interface make them ideal for a variety of applications, including personal computers, office equipment, and domestic appliances.
