ADS8519IBDBR Equivalent & Substitute Parts

Part Overview

The ADS8519IBDBR is a 16-bit Analog to Digital Converter manufactured by Texas Instruments, designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device operates with external or internal reference voltage and communicates via SPI interface. The part is currently in active production status with 2280 units available in inventory. Alternative components may be required due to supply constraints, design revisions, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS8519IBDBR is determined by strict alignment of the following critical parameters:

Core Electrical Parameters (Must Match):

• Resolution: 16 bits
• Input Configuration: Single-ended, 1 input
• Data Interface: SPI
• Architecture: SAR
• Reference Type: External and/or Internal capability
• Analog Supply Voltage: 5V
• Package Type: 28-SSOP

Allowable Variations:

• Sampling Rate: Minimum 200k samples per second (ADS8519IBDBR operates at 250k)
• Digital Supply Voltage: Range must encompass or be compatible with 1.65V ~ 5.25V
• Operating Temperature: May be narrower than -40°C ~ 85°C if application requirements permit
• Moisture Sensitivity Level: May differ based on storage and handling requirements
• Packaging Format: Tube or Tape & Reel acceptable for equivalent functionality

The LTC1609CG#PBF from Analog Devices Inc. qualifies as a substitute based on matching all core electrical parameters and package footprint compatibility.

Engineering Selection Recommendations

Primary Part: ADS8519IBDBR

• Recommended for applications requiring maximum sampling rate (250k SPS) within the extended operating temperature range (-40°C to 85°C)
• Active production status with established supply chain
• ROHS3 compliant for regulated markets

Substitute Part: LTC1609CG#PBF

• Functionally equivalent for applications operating within 0°C to 70°C temperature range
• Reduced sampling rate (200k SPS) is acceptable for applications not requiring the full 250k SPS capability
• Superior moisture sensitivity rating (MSL 1, Unlimited) provides extended shelf life and reduced handling constraints
• Both parts maintain identical electrical interface specifications and package footprint
• Both parts carry active production status and ROHS3 compliance

Selection between these parts should be based on application-specific requirements for operating temperature range and sampling rate performance.

Frequently Asked Questions (FAQ)

Q: Can LTC1609CG#PBF replace ADS8519IBDBR in all applications?

A: LTC1609CG#PBF is electrically and mechanically compatible for applications operating within 0°C to 70°C. If your application requires operation below 0°C or above 70°C, the ADS8519IBDBR is required. If your application requires sampling rates exceeding 200k SPS, the ADS8519IBDBR is required.

Q: Are the package footprints identical?

A: Yes. Both parts use 28-SSOP packaging with 0.209" width (5.30mm). PCB layout and reflow profiles remain unchanged.

Q: What is the difference in sampling rate performance?

A: ADS8519IBDBR operates at 250k samples per second. LTC1609CG#PBF operates at 200k samples per second. For applications requiring conversion rates below 200k SPS, both parts perform identically.

Q: How do the supply voltage specifications compare?

A: Both parts require 5V analog supply. ADS8519IBDBR accepts digital supply from 1.65V to 5.25V, while LTC1609CG#PBF operates at 5V digital supply. The LTC1609CG#PBF digital supply specification falls within the ADS8519IBDBR range, ensuring compatibility in 5V digital logic environments.

Q: What is the significance of the Moisture Sensitivity Level difference?

A: ADS8519IBDBR has MSL 2 (1 Year shelf life under controlled conditions). LTC1609CG#PBF has MSL 1 (Unlimited shelf life). This means LTC1609CG#PBF requires less stringent moisture control during storage and handling, reducing risk of moisture-induced failures in extended inventory scenarios.

Q: Are both parts RoHS compliant?

A: Yes. Both ADS8519IBDBR and LTC1609CG#PBF are ROHS3 compliant and suitable for regulated markets requiring lead-free components.

Q: What is the SPI interface compatibility?

A: Both parts use identical SPI data interface protocols. Firmware and software implementations require no modification when substituting between these parts.
