ADS7807UG4 Equivalent & Substitute Parts

Part Overview

The ADS7807UG4 is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 40 kSPS sampling rate and operates from a 5V supply. The device is packaged in a 28-SOIC surface mount package and supports both SPI and parallel data interfaces.

The ADS7807UG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Substitute Part Grouping Explanation

Substitute parts for the ADS7807UG4 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The following parameters determine substitution eligibility:

• Resolution: 16 bits
• Sampling Rate: 40 kSPS
• Number of Inputs: 1
• Input Type: Single Ended
• Data Interface: SPI and Parallel support
• Architecture: SAR
• Configuration: S/H-ADC with 1:1 ratio
• Number of A/D Converters: 1
• Reference Type: External and Internal
• Supply Voltages: 5V analog and digital
• Operating Temperature: -40°C to 85°C
• Package: 28-SOIC surface mount
• RoHS Status: ROHS3 Compliant

The substitute parts listed below meet all of these parameters identically and are therefore direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both ADS8507IBDW and ADS8507IDW are direct parametric equivalents to the discontinued ADS7807UG4. Selection between these two substitute parts should be based on the following factors:

Product Status: Both substitute parts are currently active products from Texas Instruments, ensuring long-term availability and continued manufacturer support compared to the discontinued ADS7807UG4.

Compliance & Certifications: All three parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 2 (1 Year), ensuring regulatory and environmental compatibility with existing designs.

Packaging & Availability: Both substitutes are supplied in tube packaging and are available in higher inventory quantities (ADS8507IBDW: 1102 pcs, ADS8507IDW: 2280 pcs) compared to the original part (1107 pcs), providing improved supply chain reliability.

Functional Equivalence: The ADS8507 series maintains 100% electrical and mechanical compatibility with the ADS7807UG4 across all specified parameters, enabling direct pin-for-pin replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can ADS8507IBDW and ADS8507IDW be used interchangeably with ADS7807UG4?

A: Yes. Both ADS8507 variants are direct parametric equivalents meeting all electrical specifications, operating conditions, and package requirements of the ADS7807UG4. No circuit modifications are required for substitution.

Q: What is the difference between ADS8507IBDW and ADS8507IDW?

A: Both parts are identical in all electrical and mechanical parameters provided in this reference. The difference lies in their part number designation, which typically reflects manufacturing date code or internal Texas Instruments classification. Both are suitable for direct substitution.

Q: Are there any compatibility concerns with the 28-SOIC package?

A: No. All three parts use the identical 28-SOIC (0.295", 7.50mm Width) surface mount package. PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

Q: Why is the ADS7807UG4 discontinued?

A: The ADS7807UG4 has been discontinued at DiGi Electronics. The ADS8507 series represents the current active product line from Texas Instruments for this functional category, offering improved availability and manufacturer support.

Q: Do the substitute parts maintain the same supply voltage requirements?

A: Yes. Both ADS8507IBDW and ADS8507IDW operate from identical 5V analog and digital supply voltages as the ADS7807UG4, with the same -40°C to 85°C operating temperature range.

Q: Are there any differences in data interface compatibility?

A: No. All three parts support identical SPI and parallel data interfaces with the same S/H-ADC configuration and 1:1 ratio, ensuring software and firmware compatibility without modification.
