ADS8505IDBRG4

Analog To Digital Converters (ADC) Overview

The ADS8505IDBRG4 is a 16-bit, 250-kSPS successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates from a single +5-V supply and features a standard ±10-V input range with an internal 2.5-V reference. The device provides full parallel data output via three-state drivers and supports both internal and external reference configurations. It is specified for operation over the industrial temperature range of -40°C to 85°C and is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'R' indicates tape and reel packaging and 'G4' denotes lead-free/RoHS compliance status. Confirm the package designator corresponds to the SOIC-28 form factor. Ensure the source documentation matches the SLAS180B datasheet revision for accurate electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit SAR ADC with a high-speed 250-kSPS sampling rate is required. It is suitable for applications needing a wide ±10-V input range without external attenuation circuitry. Consider the internal reference drift if extreme precision is needed, or utilize the external reference pin for higher stability.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8505 family of CMOS analog-to-digital converters. It is pin-compatible with the lower-speed ADS7805 and the 12-bit ADS8504/ADS7804 devices, facilitating design upgrades within existing hardware architectures.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the ADS8505IBDW and ADS8505IDW for tube packaging variants. Verify pin compatibility and electrical specifications against the target application requirements before substitution.
