GENERAL DESCRIPTION  
The ADT7516/ADT7517/ADT75191 combine a 10-bit tempera-  
ture-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.  
Power-on reset to 0 V DAC output  
Simultaneous update of outputs (LDAC function)  
On-chip, rail-to-rail output buffer amplifier  
SPI®, I2C®, QSPI™, MICROWIRE™, and DSP compatible  
4-wire serial interface  
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 μs typical.  
SMBus packet error checking (PEC) compatible  
16-lead QSOP package  
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.  
APPLICATIONS  
Portable battery-powered instruments  
Personal computers  
Smart battery chargers  
Telecommunications systems  
Electronic text equipment  
Domestic appliances  
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  
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-/  
I2C-compatible interface of the ADT7516/ADT7517/ADT7519  
make them ideal for a variety of applications, including  
personal computers, office equipment, and domestic appliances.
