ADS8412IBPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8412IBPFBTG4 is a 16-bit, 2-MSPS analog-to-digital converter (ADC) from 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 range of 2.7 V to 5.25 V. Key electrical specifications include a signal-to-noise ratio (SNR) of 86 dB, differential nonlinearity (DNL) of -1/1.5 LSB, and integral nonlinearity (INL) of +/- 2 LSB. It utilizes a parallel interface for data output and consumes approximately 155 mW of power. The component is housed in a TQFP-48 package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence according to Texas Instruments documentation. Confirm the TQFP-48 package dimensions and pinout against the official datasheet before integration. Ensure the design accounts for the specified analog and digital supply voltage ranges to maintain performance within the stated linearity parameters.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution at 2 MSPS sampling rate is required with low power consumption. It is suitable for designs needing a parallel interface and integrated clocking. Consider the TQFP-48 package size constraints and the requirement for separate analog and digital supplies. Evaluate if the 86 dB SNR meets the system noise floor requirements compared to higher-performance alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS84xx family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with the ADS8405 and ADS8411 but offers specific speed and interface characteristics tailored for mid-range data acquisition applications. The family is designed to provide precision conversion capabilities in compact packages for industrial and automotive environments.

Analog To Digital Converters (ADC) Replacement Considerations
