ADS7955SRGER

Analog To Digital Converters (ADC) Overview

The ADS7955SRGER is a micro power, 10-bit analog-to-digital converter (ADC) featuring eight single-ended input channels. It utilizes successive approximation register (SAR) architecture to achieve a sampling rate of 1 MSPS. The device operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 5.25 V. It communicates via a standard SPI interface and is housed in a 24-pin VQFN package. Key performance metrics include a signal-to-noise ratio (SNR) of 60 dB and a maximum power dissipation of 14.5 mW.

Analog To Digital Converters (ADC) Feature Summary

• Integrates eight single-ended analog inputs within a compact surface-mount package for space-constrained designs.
• Supports flexible power configurations through independent analog and digital supply voltage ranges.
• Provides high-speed data conversion at 1 MSPS while maintaining low power consumption suitable for battery-operated systems.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring multi-channel signal acquisition
• Industrial process control systems with sensor arrays
• Data acquisition modules for environmental monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GER' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the ordered component matches the exact pinout and electrical specifications defined for this variant to prevent integration errors during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended channels are required alongside moderate resolution and speed. Compare it against other members of the ADS795x family if differential inputs or higher resolution are needed. Confirm that the external reference voltage requirements align with the system's available supply rails.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS795x series of micro power ADCs. The series offers various resolutions and channel counts, sharing common architectural features such as SAR conversion and SPI interfaces. The SRGER designation specifically identifies the 8-channel, 10-bit variant in a VQFN-24 package.

Analog To Digital Converters (ADC) Replacement Considerations

Check the ADS7955SDBT for a TSSOP-30 package alternative. Verify pin compatibility and electrical parameters before substitution. Other family members like the ADS7950 or ADS7953 may serve as functional equivalents if channel count or resolution differences are acceptable.
