3 Description
The ADS7039-Q1 device is a an automotive Q100-
qualified, 10-bit, 2-MSPS, analog-to-digital converter
(ADC). The device supports a wide analog input
voltage range (2.35 V to 3.6 V) and includes a
capacitor-based, successive-approximation register
(SAR) ADC with an inherent sample-and-hold circuit.
The SPI-compatible serial interface is controlled by
the CS and SCLK signals. The input signal is
sampled with the CS falling edge and SCLK is used
for conversion and serial data output. The device
supports a wide digital supply range (1.65 V to 3.6 V),
enabling direct interface to a variety of host
controllers. The ADS7039-Q1 complies with the
JESD8-7A standard for a normal DVDD range
(1.65 V to 1.95 V).
The ADS7039-Q1 is available in an 8-pin, miniature,
VSSOP package and is specified for operation from
–40°C to +125°C. The fast sampling rate of the
ADS7039-Q1, along with miniature form-factor and
low-power consumption, makes this device suitable
for space-constrained and fast-scanning automotive
applications.
