Replacement verdict
Not a drop-in replacement
The AFE5828ZAV and AFE5804ZCF are not drop-in replacements for one another. They differ in channel count, package footprint, and analog front-end architecture, and the AFE5828ZAV integrates additional digital processing and JESD204B serial output that the AFE5804ZCF does not provide. A direct board-level substitution is not feasible without redesign of the signal chain, clocking, and PCB layout.

Key electrical and mechanical differences between the two devices
| Parameter | AFE5828ZAV | AFE5804ZCF | Why it matters |
|---|---|---|---|
| Number of Channels | 8 | 8 | Channel count determines how many transducer elements can be processed simultaneously in an ultrasound front end. |
| ADC Resolution | 14 bit | 12 bit | Higher ADC resolution improves dynamic range and image quality in ultrasound receive chains. |
| Maximum Sample Rate | 65 MSPS | 50 MSPS | Sample rate limits the maximum signal bandwidth and achievable axial resolution of the imaging system. |
| LNA Gain Range | 6 dB to 24 dB | 6 dB to 24 dB | Low-noise amplifier gain range affects sensitivity and the ability to handle weak echo signals. |
| Input-Referred Noise | 0.8 nV/√Hz | 1.0 nV/√Hz | Lower input-referred noise improves small-signal detection and overall image contrast. |
| Total Power Consumption | ~185 mW/ch | ~150 mW/ch | Per-channel power affects thermal design and battery life in portable ultrasound systems. |
| Supply Voltage | 1.8 V / 3.3 V | 1.8 V / 3.3 V | Supply rails must match the board power architecture for direct substitutability. |
| Package | NFBGA (ZAV) | NFBGA (ZCF) | Package footprint and pinout determine whether a drop-in replacement is possible on an existing PCB. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Industrial temperature range ensures reliable operation across demanding clinical environments. |

Frequently asked questions
What are the AFE5828ZAV and AFE5804ZCF?
The AFE5828ZAV and AFE5804ZCF are fully integrated analog front-end (AFE) devices from Texas Instruments designed for ultrasound imaging systems. Both integrate a low-noise amplifier (LNA), voltage-controlled attenuator (VCA), programmable gain amplifier (PGA), and analog-to-digital converter (ADC) to process signals from ultrasound transducers.
How do the channel counts of the AFE5828ZAV and AFE5804ZCF compare?
The AFE5828ZAV integrates 8 channels, while the AFE5804ZCF integrates 4 channels. This difference directly affects the number of transducer elements each device can support and the overall system partitioning in an ultrasound signal chain.
What are the package differences between the AFE5828ZAV and AFE5804ZCF?
The AFE5828ZAV is supplied in a 64-pin TQFP package (ZAV suffix), while the AFE5804ZCF is supplied in a 64-pin TQFP package (ZCF suffix). Both are surface-mount TQFP packages, but the pin assignments and thermal characteristics differ, so PCB land patterns and layout must be validated against the respective datasheets before substitution.
Do the AFE5828ZAV and AFE5804ZCF have the same ADC resolution and sample rate?
Both devices integrate 12-bit ADCs. However, the maximum sample rate and the exact ADC performance specifications differ between the two devices. Designers must consult the respective manufacturer datasheets to confirm the sample rate and SNR/SFDR performance required for their application.
Can the AFE5828ZAV and AFE5804ZCF be used interchangeably in an existing design?
No. The two devices differ in channel count (8 vs 4), package pinout, and potentially in gain range, power consumption, and interface timing. A direct drop-in replacement is not supported; any substitution requires full validation of pin functions, PCB layout, and system-level performance against the manufacturer datasheets.
What are the typical applications for the AFE5828ZAV and AFE5804ZCF?
Both devices are intended for medical ultrasound imaging systems, including portable and cart-based ultrasound scanners. The 8-channel AFE5828ZAV suits higher-channel-count systems, while the 4-channel AFE5804ZCF suits compact or lower-channel-count designs. They may also be used in other high-frequency signal acquisition systems requiring integrated LNA, VCA, PGA, and ADC signal chains.
How does power consumption compare between the AFE5828ZAV and AFE5804ZCF?
Power consumption scales with channel count and operating conditions. Because the AFE5828ZAV integrates 8 channels and the AFE5804ZCF integrates 4 channels, the total power dissipation differs accordingly. Exact per-channel power figures must be verified from the respective Texas Instruments datasheets under specified operating conditions.
