Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS1243IPWRG4 is determined by strict equivalence across the following critical parameters:

• Resolution & Architecture: 24-bit Sigma-Delta conversion
• Channel Configuration: 8 input channels with differential and single-ended support
• Sampling Rate: 15 samples per second
• Signal Conditioning: Integrated MUX-PGA-ADC configuration
• Digital Interface: SPI protocol
• Package & Pinout: 20-TSSOP form factor with identical pin assignment
• Supply Voltage Ranges: Analog (2.7V ~ 3.3V, 5V) and Digital (2.7V ~ 5.25V)
• Temperature Range: -40°C ~ 85°C operation
• Compliance: ROHS3 and REACH requirements

The ADS1243IPWT meets all these criteria as a parametric equivalent, differing only in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The ADS1243IPWT is the direct parametric equivalent for the discontinued ADS1243IPWRG4. Both devices share identical electrical specifications, pin configuration, and package dimensions. The primary distinction is product lifecycle status: the ADS1243IPWRG4 is discontinued, while the ADS1243IPWT maintains active production status with significantly higher inventory availability (66,080 units versus 990 units).

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The ADS1243IPWT is available in Cut Tape and Digi-Reel packaging formats, providing flexibility for both prototype and production volume requirements.

For new designs and ongoing production, the ADS1243IPWT is the appropriate selection. For existing designs currently using the ADS1243IPWRG4, direct substitution is electrically and mechanically compatible without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the ADS1243IPWT directly replace the ADS1243IPWRG4 without circuit changes?

A: Yes. Both devices are parametrically identical across all electrical specifications, pin assignments, and package dimensions. Direct substitution requires no circuit modifications.

Q: What is the difference between the two part numbers?
