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.
Protected by the following U.S. Patent Numbers: 6,169,442; 5,867,012;
5,764174. Other patents pending.
