ADC128S102WGMPR

Analog To Digital Converters (ADC) Overview

The ADC128S102WGMPR is a radiation-hardened, low-power, eight-channel CMOS 12-bit analog-to-digital converter. It features a successive-approximation register architecture with an internal track-and-hold circuit and supports conversion throughput rates from 50 kSPS to 1 MSPS. The device accepts up to eight input signals at inputs IN0 through IN7 and outputs straight binary data compatible with SPI, QSPI, MICROWIRE, and DSP serial interfaces. It operates with independent analog (VA) and digital (VD) supplies ranging from 2.7 V to 5.25 V. Packaged in a 16-lead ceramic SOIC, it provides high reliability for demanding environments.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix WGMPR against the manufacturer's current orderable addendum to confirm package type and grade. Confirm that the radiation hardness specifications meet the mission requirements for total ionizing dose and single-event effects. Ensure the procurement channel provides valid traceability documentation for military or aerospace-grade components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when radiation tolerance is critical for the application environment. Verify that the required sampling rate falls within the 50 kSPS to 1 MSPS range. Ensure the system design accommodates the 16-lead ceramic SOIC package dimensions and thermal characteristics. Check that the host processor supports the required serial clock frequencies up to 16 MHz.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADC128S102QML-SP family of radiation-hardened data converters. It shares core architectural similarities with other members of the series but is distinguished by its specific ceramic SOIC packaging and engineering sample status indicated by the ordering suffix.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other variants within the ADC128S102QML-SP family such as ADC128S102WGRQV or ADC128S102WRQV, provided the package form factor matches the board layout. Verify radiation specs match if replacing with non-QML parts.

Analog To Digital Converters (ADC) FAQ

What is the maximum clock frequency supported by the ADC128S102WGMPR?

The specified maximum clock frequency for the SCLK input is 16 MHz, which enables the maximum throughput rate of 1 MSPS.

How does the device handle power-down mode?

In power-down mode, CS is held high. This reduces power consumption to 0.33 µW at 3 V and 0.6 µW at 5 V, significantly lowering standby energy usage.

Is the output data format signed or unsigned?

The output serial data is in straight (natural) binary format, representing unsigned values from 0 to full scale.
