ADS5120CGHK

Analog To Digital Converters (ADC) Overview

The ADS5120CGHK is a compact octal analog-to-digital converter manufactured by Texas Instruments, designed specifically for imaging applications. It features eight independent 10-bit pipeline converters operating at a sampling rate of 40 MSPS. The device utilizes differential inputs and provides parallel digital outputs. It operates on a single 1.8 V supply for both analog and digital sections, resulting in a power dissipation of 850 mW. Key performance metrics include a signal-to-noise ratio of 58 dB, an effective number of bits of 9.2, and integral and differential nonlinearity specifications of +/- 1.5 LSB and +/- 1 LSB, respectively. It is housed in a BGA-257 Microstar package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the current lifecycle status before procurement, as the ADS5120CGHK is listed as obsolete or discontinued in available distributor records. Confirm availability through authorized channels or secondary markets if immediate sourcing is required. Ensure compatibility with the BGA-257 Microstar footprint during PCB layout planning. Check for moisture sensitivity levels and reflow soldering requirements specific to this package type.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS5120CGHK when an application demands eight simultaneous 10-bit conversion channels at 40 MSPS with low power constraints. This component is suitable for designs where board real estate is limited due to its integrated octal configuration. Consider the parallel interface requirement and the need for differential signaling when evaluating system architecture. Verify that the 1.8 V supply voltage aligns with the rest of the system's power distribution network.

Analog To Digital Converters (ADC) Part Context

The ADS5120 belongs to the ADS5120 series of analog-to-digital converters from Texas Instruments. It is part of a family of compact, multi-channel ADCs aimed at reducing complexity in imaging and data acquisition systems. The CGHK suffix indicates the specific package variant (BGA-257 Microstar) and temperature range (Commercial, 0°C to +70°C). Development tools such as the ADS5120EVM are available for evaluation purposes.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the ADS5120CGHK is listed as obsolete, engineers should consult Texas Instruments for recommended alternatives or evaluate other members of the ADS5120 series if pin-compatible options exist. System redesign may be necessary if direct substitutes are unavailable.
