Input range: 0 V to 2.28 V Temperature range: 40C to +120C GENERAL DESCRIPTION Temperature sensor accuracy: 0.5C typ 1 The ADT7516/ADT7517/ADT7519 combine a 10-bit tempera- Supply range: 2.7 V to 5.5 V ture-to-digital converter, a 10-bit 4-channel ADC, and a quad DAC output range: 0 V to 2 V REF 12-/10-/8-bit DAC, respectively, in a 16-lead QSOP package. Power-down current: <10 A The parts also include a band gap temperature sensor and a Internal 2.28 V option REF 10-bit ADC to monitor and digitize the temperature reading to Double-buffered input logic a resolution of 0.25C. Buffered reference input Power-on reset to 0 V DAC output The ADT7516/ADT7517/ADT7519 operate from a single 2.7 V Simultaneous update of outputs (LDAC function) to 5.5 V supply. The input voltage range on the ADC channels is On-chip, rail-to-rail output buffer amplifier 0 V to 2.28 V, and the input bandwidth is dc. The reference for 2 SPI , I C , QSPI, MICROWIRE, and DSP compatible the ADC channels is derived internally. The output voltage of 4-wire serial interface the DAC ranges from 0 V to VDD, with an output voltage settling SMBus packet error checking (PEC) compatible time of 7 s typical. 16-lead QSOP package The ADT7516/ADT7517/ADT7519 provide two serial interface options: a 4-wire serial interface that is compatible with SPI, APPLICATIONS QSPI, MICROWIRE, and DSP interface standards, and a 2-wire Portable battery-powered instruments 2 SMBus/I C interface. They feature a standby mode that is Personal computers controlled through the serial interface. Smart battery chargers Telecommunications systems The reference for the four DACs is derived either internally or Electronic text equipment from a reference pin. The outputs of all DACs can be updated Domestic appliances simultaneously using the software LDAC function or the Process control LDAC external pin. The ADT7516/ADT7517/ADT7519 incorporate a power-on reset circuit, ensuring that the DAC output powers up to 0 V and remains there until a valid write takes place. The wide supply voltage range, low supply current, and SPI-/ 2 I C-compatible interface of the ADT7516/ADT7517/ADT7519 make them ideal for a variety of applications, including personal computers, office equipment, and domestic appliances. 1 Protected by U.S. Patent Numbers: 6,169,442 5,867,012 and 5,764,174.
