ADS8689IPWR

Analog To Digital Converters (ADC) Overview

The ADS8689IPWR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 100 kSPS and features an SPI digital interface. The device accepts single-ended inputs and includes an integrated programmable gain amplifier (PGA), internal oscillator, and over-voltage protection. It requires an analog supply voltage between 4.75 V and 5.25 V and a digital supply voltage ranging from 1.65 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) and SINAD of 92 dB, with a typical power consumption of 21 mW. The component is housed in a TSSOP-16 package and supports an operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated analog front-end with programmable gain amplifier for flexible input scaling
• Built-in over-voltage protection to safeguard against input signal excursions
• On-chip oscillator eliminates the need for external clock generation components
• SPI-compatible serial interface supporting daisy-chain configurations

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Portable instrumentation utilizing single-supply operation
• Medical equipment demanding precise signal digitization
• Data logging applications with moderate throughput requirements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPWR' corresponds to the TSSOP-16 package and reel packaging configuration as listed in official Texas Instruments documentation. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the ordering part number matches the exact pinout and electrical specifications defined in the current datasheet revision to avoid integration errors.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution is required at speeds up to 100 kSPS. It is suitable for designs needing integrated PGA functionality and over-voltage protection without external discrete components. Consider the dual-supply requirement (analog vs. digital) and the TSSOP-16 footprint constraints during PCB layout planning.

Analog To Digital Converters (ADC) Part Context

The ADS8689 belongs to the ADS868x family of 16-bit SAR ADCs from Texas Instruments. While other members like the ADS8688 offer multi-channel capabilities, the ADS8689 is specifically configured as a single-channel device. This variant focuses on providing a compact solution with integrated signal conditioning features for cost-sensitive and space-constrained applications.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Texas Instruments ADS868x datasheet for direct pin-to-pin or functional equivalents within the same family. Verify that any substitute maintains the 16-bit resolution, 100 kSPS speed, and TSSOP-16 package compatibility.
