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.
