ADS8412IPFBT

Analog To Digital Converters (ADC) Overview

The ADS8412IPFBT is a 16-bit, 2-MHz successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an internal 4.096-V reference and onboard buffer, supporting unipolar differential input ranges from Vref to −Vref. The device operates with a 5-V analog supply (+VA) and a wide digital supply (+VBD) ranging from 2.7 V to 5.25 V. Key electrical parameters include a typical power dissipation of 175 mW at 2 MHz, a conversion time of 360 ns, and an acquisition time of 100 ns. It provides zero-latency data output via a high-speed parallel interface.

Analog To Digital Converters (ADC) Feature Summary

• Transducer Interface

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific linearity grade required for the application. The 'I' suffix denotes ±6 LSB INL and ±3 LSB DNL, while the 'B' suffix offers tighter tolerances of ±3.5 LSB INL and ±2 LSB DNL. Confirm that the tape and reel quantity matches the production needs, as the IPFBT variant is supplied in reels of 250 units.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS8412IPFBT when a 16-bit resolution and 2-MHz throughput are required without external reference components. Ensure the driving source can charge the 25-pF input capacitance within the 100-ns acquisition time. Verify that the system logic levels align with the +VBD supply voltage, which supports both 3-V and 5-V CMOS interfaces.
