ADS8401IBPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8401IBPFBTG4 is a 16-bit, 1.25 MSPS successive approximation register (SAR) analog-to-digital converter featuring a unipolar single-ended input range of 0 V to Vref. It integrates a 4.096-V internal reference and buffer. The device provides zero-latency conversion with a throughput rate of 1.25 MHz. It supports an 8- or 16-bit parallel data interface and operates over the industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current documentation to confirm compliance with RoHS standards and lead-free material specifications. Ensure the ordering code matches the required linearity grade ('I' for ±6 LSB INL) and package type (TQFP). Confirm availability through authorized channels as production status may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed, low-latency ADC with a parallel interface is required. The integrated reference simplifies design by eliminating external components. Ensure the system can accommodate the 48-pin TQFP package and that the digital supply voltage (+VBD) meets the minimum requirement relative to the analog supply (+VA).

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS840x family of high-speed SAR ADCs from Texas Instruments. The 'I' designation indicates a maximum integral nonlinearity of ±6 LSB. The 'BPFB' code identifies the 48-lead plastic thin quad flatpack (TQFP) package. The 'TG4' suffix typically denotes environmental compliance and lead-free construction.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADS8401IPFBR (tape and reel packaging) or the ADS8401IPFBT. For different linearity grades, the ADS8401IB variant offers tighter ±3.5 LSB INL but requires verification of timing and power characteristics.
