ADS7809UB/1K

Analog To Digital Converters (ADC) Overview

The ADS7809UB/1K is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 100 kS/s and supports both serial and parallel interfaces. The device functions on a single 5 V supply, with analog and digital power rails ranging from 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 88 dB and a total harmonic distortion (SINAD) of 88 dB. It features an internal or external reference option and operates within a temperature range of -40°C to +85°C. The component is housed in a 20-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'UB/1K' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and pinout compatibility. Ensure that the ordering information matches the exact commercial grade specifications, including the operating temperature range and interface requirements, before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input architecture with 16-bit resolution is required at speeds up to 100 kS/s. It is suitable for designs needing a 5 V supply and flexible digital connectivity options. Consider alternative models if differential inputs or lower power consumption are primary constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS780x series of CMOS sampling analog-to-digital converters. The series is characterized by its combination of high accuracy and moderate speed, targeting applications where precision is critical but ultra-high throughput is not the primary requirement. The UB variant typically denotes a specific package and reel configuration within the standard product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the ADS7809U. For different interface requirements, consider the ADS7805UB/1K for parallel interfaces or the ADS7804U/1K for 12-bit resolution needs. Verify pin compatibility and electrical specifications before substitution.
