ADS8412IBPFBT

Analog To Digital Converters (ADC) Overview

The ADS8412IBPFBT is a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-channel pseudo-differential input and operates at a sampling rate of 2 MSPS. The device utilizes a parallel interface for data output and includes an internal reference. It supports an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 2.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 90 dB, differential nonlinearity (DNL) of -1/1.5 LSB, and integral nonlinearity (INL) of +/- 2 LSB. Power consumption is rated at 170 mW. The component is housed in a TQFP-48 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal reference simplifies system design by reducing external component count.
• High-speed parallel interface enables efficient data transfer for high-throughput applications.
• Low power consumption architecture supports battery-operated or thermally constrained environments.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring high resolution and low power.
• Industrial process control systems with multi-channel data acquisition needs.
• Vibration monitoring and acoustic emission testing equipment.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BT' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through the manufacturer's current documentation, as lead-free variants may carry additional suffixes such as 'G4'. Ensure the ordered part matches the industrial temperature grade (-40°C to +85°C) required for the application environment. Cross-reference the datasheet revision date to ensure compatibility with existing design files.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 2 MSPS sampling rate are required for single-channel applications. Compare against the ADS8405 if lower speed (1.25 MSPS) is acceptable, or the ADS8422 if higher speed (4 MSPS) and fully differential inputs are needed. Consider the parallel interface requirement versus serial alternatives like the ADS8328 if pin count is limited. Verify that the 5V analog supply aligns with the system power architecture.

Analog To Digital Converters (ADC) Part Context

The ADS8412 belongs to the ADS84xx family of micro-power sampling ADCs from Texas Instruments. This series is designed for applications demanding high accuracy and moderate speed. The IBPFBT designation identifies the industrial temperature range variant in a 48-pin TQFP package. It shares architectural similarities with the ADS8405 and ADS8411 but offers distinct performance trade-offs in speed and input configuration within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8412IBPFBTG4 is a confirmed lead-free replacement variant with identical electrical specifications. For functional upgrades, the ADS8422IBPFBT offers higher speed but requires fully differential inputs. Downgrade options include the ADS8405IBPFBT for lower power at reduced sampling rates. Pin compatibility must be verified when substituting across different families.
