ADS8402IPFBT

Analog To Digital Converters (ADC) Overview

The ADS8402IPFBT is a 16-bit, 1.25 MSPS analog-to-digital converter (ADC) featuring a unipolar differential input architecture and an integrated parallel interface. It incorporates an onboard 4.096-V reference with a dedicated buffer. The device utilizes a capacitor-based successive approximation register (SAR) structure with inherent sample-and-hold capabilities. Key electrical specifications include a typical signal-to-noise ratio of 90 dB, a total harmonic distortion of -95 dB, and a power dissipation of 155 mW at maximum throughput. It operates within an industrial temperature range of –40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific linearity grade required for the application. The 'I' suffix denotes ±6 LSB integral nonlinearity, while the 'B' suffix indicates ±3.5 LSB. Ensure the ordering suffix matches the desired performance tier and packaging quantity before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS8402IPFBT when a 16-bit resolution and 1.25 MSPS sampling rate are required with a unipolar differential input. This model includes an internal reference, eliminating the need for external voltage references in standard applications. Verify that the system supports a high-speed parallel interface and accommodates the 48-pin TQFP package constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS840x family of micro-power sampling ADCs from Texas Instruments. It shares architectural similarities with models like the ADS8405 but differs in input configuration and reference integration. The IPFBT designation specifically identifies the industrial temperature grade version packaged in a tape and reel format.
