ADS8405IBPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8405IBPFBTG4 is a 16-bit, 1.25 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 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. Power consumption is specified at 155 mW, with a maximum power dissipation of 170 mW. It utilizes a parallel interface and is housed in a TQFP-48 package, operating within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal oscillator simplifies system design by eliminating external clock components.
• Supports both pseudo-differential and single-ended input configurations for flexible signal interfacing.
• Offers high accuracy with 16-bit resolution and low nonlinearity errors suitable for precision applications.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status when sourcing. Confirm the TQFP-48 package availability and ensure the supplier provides official datasheets matching the ADS8405IBPFBTG4 designation. Check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 16-bit conversion is required with low power consumption. Compare SNR and INL specifications against application noise floors. Ensure the parallel interface timing constraints align with the host microcontroller or DSP capabilities. Verify that the dual-supply voltage requirements fit the system power architecture.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8405 family of high-speed, low-power ADCs. It shares architectural similarities with other SAR-based converters but is distinguished by its specific 1.25 MSPS sampling rate and integrated oscillator feature. The IBPFBT variant denotes the industrial temperature range and tape-and-reel packaging format.
