Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD4022BCPZ-RL7 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• 20-bit resolution and SAR architecture
• 500 kSPS sampling rate
• Single differential input configuration
• Support for DSP, MICROWIRE™, QSPI™, and SPI™ interfaces
• Analog supply voltage range of 1.71V ~ 1.89V
• Digital supply voltage range of 1.71V ~ 5.5V
• Operating temperature range of -40°C ~ 125°C
• 10-LFCSP-WD (3x3) package with exposed pad
• Surface mount mounting type
• External reference type

Parts meeting all these criteria are classified as parametric equivalents and can be used interchangeably in applications designed for the AD4022BCPZ-RL7.
