Replacement verdict
Not a drop-in replacement
The AFE5816ZAV and AFE5804ZCF are not drop-in replacements for one another. They differ in channel count, package footprint, and analog front-end architecture, and neither device can be substituted directly without a full board redesign and validation of the signal chain.

Key electrical and mechanical differences between the two devices
| Parameter | AFE5816ZAV | AFE5804ZCF | Why it matters |
|---|---|---|---|
| Number of Channels | 16 | 8 | Channel count determines how many transducer elements or signal paths the AFE can support; a 16-channel device can serve twice the channels of an 8-channel device, affecting system architecture and board space. |
| Analog-to-Digital Converter Resolution | 14 bit | 12 bit | Higher ADC resolution provides greater dynamic range and finer quantization, improving image quality and small-signal detection in ultrasound receive chains. |
| Maximum Sampling Rate | 65 MSPS | 50 MSPS | Sampling rate sets the maximum signal bandwidth and Nyquist limit; a higher rate supports wider-band transducers and better time resolution. |
| Low-Noise Amplifier (LNA) Gain Range | 12 dB to 30 dB | 10 dB to 30 dB | LNA gain range affects the ability to handle both weak and strong echoes; a wider or shifted range influences sensitivity and overload performance. |
| Time-Gain Compensation (TGC) Range | 40 dB | 40 dB | TGC compensates for depth-dependent attenuation; matching range ensures comparable compensation capability across the imaging depth. |
| Continuous Wave (CW) Doppler Support | Yes | Yes | CW Doppler capability enables blood-flow velocity measurement; both devices supporting it means Doppler functionality is preserved. |
| Package Type | NFBGA (ZAV) | NFBGA (ZCF) | Package footprint and pinout determine PCB layout compatibility; different package codes may require board redesign even if electrically similar. |
| Supply Voltage (Analog) | 1.8 V / 3.3 V | 1.8 V / 3.3 V | Supply rail requirements affect power supply design and compatibility with existing board power trees. |
| Power Consumption per Channel | Approx. 90 mW/ch | Approx. 115 mW/ch | Per-channel power affects thermal design and battery life in portable ultrasound systems; lower power enables denser channel counts. |

Frequently asked questions
What are the primary differences between the AFE5816ZAV and AFE5804ZCF?
The AFE5816ZAV is an 8-channel fully integrated analog front end with a 14-bit ADC and CW Doppler processing, while the AFE5804ZCF is an 8-channel analog front end with a 12-bit ADC. The AFE5816ZAV offers higher ADC resolution and integrated digital processing features, whereas the AFE5804ZCF is a lower-resolution, lower-power alternative for ultrasound signal chains.
Do the AFE5816ZAV and AFE5804ZCF have the same number of channels?
Yes. Both devices are 8-channel analog front ends intended for ultrasound and medical imaging applications, providing eight independent receive channels per package.
Are the AFE5816ZAV and AFE5804ZCF pin-to-pin compatible?
No. The AFE5816ZAV is supplied in a 289-ball NFBGA package, while the AFE5804ZCF is supplied in a 100-ball NFBGA package. The different package sizes and ball counts mean they are not pin-to-pin compatible and cannot be directly substituted on the same PCB footprint.
What ADC resolution does each device provide?
The AFE5816ZAV integrates a 14-bit analog-to-digital converter per channel, while the AFE5804ZCF integrates a 12-bit analog-to-digital converter per channel. The higher resolution of the AFE5816ZAV supports improved dynamic range in demanding imaging applications.
Which device supports continuous wave (CW) Doppler processing?
The AFE5816ZAV includes integrated continuous wave (CW) Doppler processing, making it suitable for ultrasound systems requiring CW Doppler capability. The AFE5804ZCF does not include integrated CW Doppler processing.
How do the power consumption figures compare between the AFE5816ZAV and AFE5804ZCF?
The AFE5804ZCF is designed as a lower-power 12-bit analog front end, while the AFE5816ZAV, with its 14-bit ADC and integrated CW Doppler processing, consumes more power per channel. Designers should consult the respective manufacturer datasheets for exact per-channel power figures under specific operating conditions.
Can the AFE5816ZAV and AFE5804ZCF be used in the same ultrasound system design?
They are not interchangeable in a single design without significant rework. The AFE5816ZAV offers higher ADC resolution and integrated CW Doppler, while the AFE5804ZCF is a lower-resolution, lower-power device in a smaller package. A system designed for one would require PCB, firmware, and signal-chain changes to accommodate the other.
