AD7292BCPZ Equivalent & Substitute Parts

Part Overview

The AD7292BCPZ is a 10-bit Analog to Digital Converter manufactured by Analog Devices Inc., designed for data acquisition applications. It features 1 or 8 input channels with differential and single-ended input types, operating at a 625 kHz sampling rate with a SAR (Successive Approximation Register) architecture. The device is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the AD7292BCPZ is based on the following critical parameters that determine functional equivalence:

• Data Interface Compatibility: SPI protocol support
• Operating Temperature Range: -40°C to 125°C
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: MSL 3 (168 Hours)
• Manufacturer: Analog Devices Inc.
• Supply Voltage Compatibility: Digital supply range overlap

The AD7293BCPZ is identified as a substitute part within the Analog Devices product family. However, this part exhibits significant architectural differences from the AD7292BCPZ, including different resolution (12-bit vs. 10-bit), different package size (56-LFCSP-WQ vs. 36-LFCSP-WQ), and different functional classification (Power Amplifier vs. ADC). Substitution is not recommended based on functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The AD7292BCPZ is obsolete and no longer in active production. The AD7293BCPZ is available as an active product from Analog Devices Inc. and maintains MSL 3 compliance equivalent to the original part.

However, direct functional substitution is not supported due to architectural differences. The AD7293BCPZ is classified as a Power Amplifier with 12-bit resolution, whereas the AD7292BCPZ is a 10-bit ADC. The package footprint differs (56-pin vs. 36-pin), requiring PCB redesign. The AD7293BCPZ operates with ±4.5V ~ 5.5V supply voltage, differing from the AD7292BCPZ supply specifications.

For applications requiring the AD7292BCPZ, direct replacement is not feasible. Alternative approaches include sourcing remaining inventory of the original part or conducting a full system redesign with a functionally equivalent active ADC from Analog Devices Inc. or alternative manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the AD7293BCPZ directly replace the AD7292BCPZ in existing designs?

A: No. The AD7293BCPZ is a different device class (Power Amplifier vs. ADC) with different pin counts, package size, and electrical specifications. PCB redesign and firmware modification would be required.

Q: What is the primary reason the AD7292BCPZ is obsolete?

A: The product status is listed as obsolete. Analog Devices Inc. has discontinued this part number.

Q: Are there package compatibility considerations between these parts?

A: Yes. The AD7292BCPZ uses a 36-LFCSP-WQ (6x6) package, while the AD7293BCPZ uses a 56-LFCSP-WQ (8x8) package. These are not pin-compatible and require different PCB layouts.

Q: Do both parts share the same moisture sensitivity requirements?

A: Yes. Both parts have MSL 3 (168 Hours) classification, indicating identical moisture handling and storage requirements.

Q: What supply voltage differences exist between these parts?

A: The AD7292BCPZ requires 5V analog supply and 1.8V ~ 5.25V digital supply. The AD7293BCPZ requires ±4.5V ~ 5.5V supply voltage. These specifications are not compatible.

Q: Are both parts RoHS compliant?

A: The AD7293BCPZ is explicitly listed as ROHS3 Compliant. Compliance information for the AD7292BCPZ is not provided in the available data.
