ADS5120CZHK

Analog To Digital Converters (ADC) Overview

The ADS5120CZHK is a low-power, 8-channel, 10-bit CMOS Analog-to-Digital Converter (ADC) operating at 40MSPS. It features simultaneous sampling of eight differential analog inputs with a 1Vpp input range. The device operates from a single 1.8V supply for analog and digital cores, while supporting flexible 1.8V or 3.3V digital I/O via the DRVDD pin. Key electrical parameters include a Signal-to-Noise Ratio (SNR) of 58dB at 20MHz input frequency, an Effective Number of Bits (ENOB) of 9.2 bits, and a typical power dissipation of 794mW to 850mW. The component utilizes a pipeline architecture with digital error correction and is housed in a 257-lead MicroSTAR BGA package.

• Portable instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the ZHK suffix indicates RoHS-compliant packaging compared to the standard GHK variant. Confirm availability status as production data may vary. Ensure handling precautions are observed due to Electrostatic Discharge (ESD) sensitivity. Check for moisture sensitivity levels if storage conditions exceed manufacturer recommendations.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-density signal processing in low-power environments. Ensure the design supports a 1.8V analog supply and accommodates either 1.8V or 3.3V digital logic levels. Verify that the PCB layout can support the 257-lead MicroSTAR BGA footprint with 0.8mm ball pitch. Consider thermal management for power dissipation up to 850mW.

Analog To Digital Converters (ADC) Part Context

The ADS5120CZHK belongs to the ADS5120 family of high-speed, multi-channel ADCs manufactured by Texas Instruments. The 'ZHK' ordering suffix specifically denotes the RoHS-compliant version of the device, packaged in a 257-lead Plastic MicroSTAR BGA. This variant maintains identical electrical specifications to the non-RoHS GHK version but complies with environmental directives.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5120CGHK is the direct non-RoHS equivalent within the same package and specification set. No other functional substitutes are documented in the provided datasheet.
