ADS8412IBPFBR

Analog To Digital Converters (ADC) Overview

The ADS8412IBPFBR is a 16-bit, 2 MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a single pseudo-differential or single-ended input channel. The device operates with 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. It consumes 155 mW of power at 4 MHz and includes an internal oscillator. The component is housed in a TQFP-48 package and supports parallel interface communication.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IBPFBR corresponds to the tape-and-reel packaging format when ordering. Confirm that the required operating temperature range aligns with industrial specifications. Ensure the host system provides stable 5V analog and compatible digital logic levels. Check for moisture sensitivity level requirements during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and 2 MSPS throughput are required with minimal external reference circuitry. Consider the parallel interface compatibility with the target processing unit. Evaluate the power budget against the 155 mW consumption figure. Compare against higher-speed alternatives like the ADS8422 if additional timing margin is needed for data transfer.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS84xx series of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with the ADS8405 but offers higher sampling rates and integrated reference capabilities. The device is designed for applications demanding precision and speed in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8422 serves as a verified alternative within the same family, offering 4 MHz operation and lower power consumption. The ADS8405 is another related model but operates at a lower 1.25 MSPS rate. Verify pinout and software compatibility before substituting these parts.
