ADS8405IBPFBR

Analog To Digital Converters (ADC) Overview

The ADS8405IBPFBR is a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-channel input supporting pseudo-differential or single-ended configurations with a sampling rate of 1.25 MSPS. 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 86 dB, differential nonlinearity (DNL) of -1/1.5 LSB, and integral nonlinearity (INL) of +/- 2 LSB. It utilizes a parallel interface and includes an internal oscillator. Power consumption is specified at 155 mW, with a maximum power dissipation of 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) Procurement Notes

Verify the specific suffix 'BR' indicates tape and reel packaging when sourcing. Confirm that the operating voltage requirements align with system design constraints. Ensure ESD protection measures are implemented during handling due to humidity sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with existing design documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between high resolution and moderate speed is required. Consider the parallel interface complexity against available microcontroller GPIO resources. Evaluate the power budget against the 155 mW consumption figure. Compare performance metrics such as SNR and linearity against alternative SAR ADCs if stricter noise specifications are necessary.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8405 series of 16-bit ADCs from Texas Instruments.
