3 Description
The ADC128S052x device is a low-power, eight-
channel CMOS 12-bit analog-to-digital converter specified for conversion throughput rates of
200 kSPS to 500 kSPS. The converter is based on a
successive-approximation register architecture with
an internal track-and-hold circuit. It can be configured
to accept up to eight input signals at inputs IN0
through IN7.
The output serial data is straight binary and is
compatible with several standards, such as SPI, QSPI, MICROWIRE, and many common DSP serial
interfaces.
The ADC128S052x may be operated with
independent analog and digital supplies. The analog
supply (VA) can range from 2.7 V to 5.25 V, and the
digital supply (VD) can range from 2.7 V to VA.
Normal power consumption using a 3-V or
5-V supply is 1.6 mW and 8.7 mW, respectively. The power-down feature reduces the power consumption
to 0.06 μW using a 3-V supply and 0.25 μW using a
5-V supply.
The ADC128S052x is packaged in a 16-pin TSSOP
package. The ADC128S052 is ensured over the
extended industrial temperature range of −40°C to
+105°C while the ADC128S052-Q1 is ensured to an AECQ100 Grade-1 automotive temperature range of
−40°C to +125°C.
