ADS7807P Equivalent & Substitute Parts

Part Overview

The ADS7807P is a 16-bit Analog to Digital Converter (ADC) with a single-ended input, SAR architecture, and 40k samples per second sampling rate. Manufactured by Texas Instruments, this component operates on 5V supply for both analog and digital domains with external or internal reference capability. The ADS7807P is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS7807P is determined by electrical and functional equivalence across the following critical parameters:

• Resolution: 16-bit ADC
• Sampling Rate: 40k samples per second
• Input Configuration: Single-ended input
• Data Interface: SPI and Parallel support
• Architecture: SAR-based conversion
• Reference Options: External and internal reference capability
• Supply Voltage: 5V analog and digital supply
• Operating Temperature Range: -40°C to 85°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The ADS8507IDW meets all electrical and functional requirements as a direct substitute. The primary difference is packaging and mounting technology: the ADS8507IDW uses 28-SOIC surface-mount packaging versus the through-hole 28-DIP of the original part.

Parameter Comparison

Engineering Selection Recommendations

The ADS8507IDW is the direct functional equivalent for the obsolete ADS7807P. Both components share identical electrical specifications, resolution, sampling rate, and interface capabilities. The ADS8507IDW carries active product status from Texas Instruments, ensuring long-term availability and support.

Selection of the ADS8507IDW requires PCB redesign to accommodate surface-mount 28-SOIC packaging in place of through-hole 28-DIP. Both components maintain ROHS3 compliance and REACH unaffected status. The ADS8507IDW provides improved moisture sensitivity rating (MSL 2 versus MSL 3), extending shelf life and reducing handling constraints during manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the ADS8507IDW directly replace the ADS7807P without circuit modification?

A: Electrical and functional compatibility is complete. Pin configuration and signal levels are identical. However, PCB layout modification is required due to different package types: 28-DIP (through-hole) versus 28-SOIC (surface-mount). Footprint redesign is necessary.

Q: What is the primary reason for substitution?

A: The ADS7807P is classified as obsolete. The ADS8507IDW is an active product offering identical electrical performance with improved availability and manufacturing support.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. The ADS8507IDW has a lower moisture sensitivity level (MSL 2 versus MSL 3), providing better protection during storage and handling.

Q: What packaging considerations apply to this substitution?

A: The ADS7807P uses through-hole 28-DIP packaging suitable for breadboard and legacy PCB designs. The ADS8507IDW uses surface-mount 28-SOIC packaging, requiring SMT assembly equipment and updated PCB design. Both packages maintain identical pin count and signal compatibility.

Q: Is the ADS8507IDW available in other package options?

A: The provided data specifies ADS8507IDW in 28-SOIC packaging. Consult the Texas Instruments product family for alternative package options within the ADS8507 series.
