ADS7807UB/1K

Analog To Digital Converters (ADC) Overview

The ADS7807UB/1K is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single 5V supply with analog and digital voltage ranges of 4.75 V to 5.25 V. The device features a sampling rate of 40 kS/s and supports both parallel and SPI serial interfaces. It has a single-ended input configuration and achieves an SNR of 88 dB. Power consumption is typically 28 mW, with a maximum power dissipation of 35 mW. The component is housed in a 28-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1K' indicates reel packaging containing 1000 units, distinct from tube-packaged variants. Confirm RoHS compliance status through official documentation. Ensure the SOIC-28 package dimensions match PCB footprint requirements. Validate operating temperature range specifications against environmental constraints before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 16-bit resolution and 40 kS/s throughput are required. Choose between parallel or serial interface based on microcontroller pin availability. Consider the 28-pin SOIC package for surface mount assembly. Verify power supply stability within the 4.75 V to 5.25 V range to maintain specified performance metrics.

Analog To Digital Converters (ADC) Part Context

The ADS7807 belongs to the ADS78xx family of CMOS sampling ADCs. This series emphasizes low power consumption and high accuracy. The UB variant denotes a specific commercial grade version. The /1K suffix specifies tape and reel packaging for automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7809 offers similar 16-bit resolution but with a higher 100 kS/s sampling rate and SOIC-20 package. ADS7804 provides 12-bit resolution at 100 kS/s. Check pin compatibility and interface requirements when substituting.
