Replacement verdict
Compatible functional replacement candidate
The AFE5808AZCF and AFE5808ZCF are functionally equivalent fully integrated analog front-end devices for ultrasound signal chains, sharing the same channel count, package footprint, supply architecture, and operating temperature range. The AFE5808AZCF is the later-revision release of the same base part, so it can serve as a direct functional replacement for the AFE5808ZCF in existing and new ultrasound system designs, subject to final validation of revision-specific performance characteristics against the system requirements.

Frequently asked questions
What is the difference between the AFE5808AZCF and the AFE5808ZCF?
The AFE5808AZCF and AFE5808ZCF are both 8-channel ultrasound analog front ends (AFEs) from Texas Instruments in a 135-ball BGA (ZCF) package. The suffix difference reflects a device revision/variant ordering code; both share the same core AFE5808 architecture (LNA, VGA, PGA, and 12-bit ADC per channel). Designers should confirm the exact revision and any datasheet errata differences with the TI product page before finalizing a design.
Are the AFE5808AZCF and AFE5808ZCF pin-to-pin and package compatible?
Both devices are offered in the same ZCF package designation (135-ball BGA), so the package footprint and ball map are consistent with the AFE5808 family. Because the "A" suffix denotes a specific ordering variant, always verify the exact ball assignment and package drawing in the respective TI datasheet before treating them as drop-in replacements.
How many channels and what resolution do these AFEs provide?
Both the AFE5808AZCF and AFE5808ZCF are 8-channel ultrasound AFEs, each channel integrating a low-noise amplifier (LNA), a voltage-controlled attenuator (VCA), a programmable gain amplifier (PGA), and a 12-bit analog-to-digital converter (ADC). This per-channel signal chain is intended for multi-element ultrasound receive paths.
What is the maximum ADC sampling rate of the AFE5808 family?
The AFE5808 family 12-bit ADCs support sampling rates up to 65 MSPS, which is the rated maximum conversion rate for these devices. Confirm the exact rated speed in the specific device datasheet, as operating conditions and revision variants should be validated against TI documentation.
What analog supply voltages do the AFE5808AZCF and AFE5808ZCF require?
The AFE5808 family typically operates from a 3.3 V analog supply and a 1.8 V digital supply, with an additional negative supply for the LNA/VCA stage as specified in the datasheet. Always consult the TI datasheet for the exact recommended supply rails and tolerances for the specific ordering variant.
Can the AFE5808AZCF and AFE5808ZCF be used interchangeably in an existing design?
Because both are AFE5808-family devices in the same ZCF package, they are generally interchangeable at the footprint level, but the "A" ordering suffix may indicate a revision or screening difference. Validate any differences in electrical specifications, errata, and operating conditions against the TI datasheet for each variant before substituting one for the other in production.
What interface does the AFE5808 family use to output converted data?
The AFE5808 family provides a serial LVDS output interface for the ADC data, supporting low-voltage differential signaling to the downstream FPGA or receiver. Refer to the TI datasheet for the exact LVDS timing, lane configuration, and clocking requirements of the specific ordering variant.
