ADS8406IPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8406IPFBTG4 is a 16-bit, 1.25 MSPS analog-to-digital converter featuring a pseudo-bipolar, fully differential input architecture and an integrated 4.096-V reference. It utilizes a capacitor-based successive approximation register (SAR) structure with inherent sample-and-hold functionality. The device supports a high-speed parallel interface with full 16-bit data output or an 8-bit option via two read cycles. Powered by a single 5-V analog supply and a 2.7-V to 5.25-V digital supply, it consumes 155 mW at maximum throughput. Characterized for industrial operation from -40°C to +85°C, it is housed in a 48-lead TQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and environmental standards as per Texas Instruments specifications. Confirm the IPFBT tape and reel packaging quantity matches project requirements. Ensure the industrial temperature grade (-40°C to +85°C) aligns with system operating conditions. Cross-reference the specific ordering code against current manufacturer documentation to confirm availability status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed, high-resolution ADC with differential inputs is required. The internal reference simplifies design by eliminating external precision references. Consider the 48-pin TQFP package constraints for PCB layout. Verify that the host system can support the parallel interface timing requirements, specifically the CONVST and RD signal dependencies for data acquisition.

Analog To Digital Converters (ADC) Part Context

The ADS8406 belongs to the High-Speed SAR Converter Family, positioned alongside models like the ADS8405 and ADS8412. It shares pin compatibility with these related devices, facilitating design upgrades or variations within the same product line. The family focuses on balancing speed and resolution for demanding data conversion applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8406 is pin-compatible with the ADS8405 and ADS8412. When substituting, verify that the alternative model's linearity specifications (INL/DNL) and input architecture (pseudo-differential vs. pseudo-bipolar) meet the circuit requirements.
