The ADT7516 series 10-bit Temperature-to-Digital Converter with a 10-bit 4-channel ADC and a quad 12-bit DAC in a single IC. 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 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 0V to VDD, with an output voltage settling time of 7μs typical. The ADT7516 provides 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 can be updated simultaneously using the software LDAC function or the external LDAC pin.
