Replacement verdict
Compatible functional replacement candidate
The AFE5828ZAV and AFE5803ZCF are both octal-channel ultrasound analog front ends with integrated continuous-wave Doppler capability, but they differ in package footprint, channel-count scalability, and power/interface configuration. The AFE5828ZAV is a viable functional candidate for the AFE5803ZCF only after validating package compatibility, clocking, and power-supply requirements against the target design.

Frequently asked questions
What are the AFE5828ZAV and AFE5803ZCF?
The AFE5828ZAV is an 8-channel fully integrated analog front end (AFE) for ultrasound from Texas Instruments, and the AFE5803ZCF is a fully integrated 8-channel AFE for ultrasound also from Texas Instruments. Both integrate a low-noise amplifier (LNA), voltage-controlled attenuator (VCA), programmable gain amplifier (PGA), and analog-to-digital converter (ADC) per channel.
How do the channel counts and package types compare between the AFE5828ZAV and AFE5803ZCF?
Both devices are 8-channel AFEs. The AFE5828ZAV is supplied in a ZAV package (a 289-ball NFBGA), while the AFE5803ZCF is supplied in a ZCF package (a 135-ball NFBGA). The different package footprints and ball counts mean the two are not drop-in replacements for each other.
What are the key differences in ADC resolution and sampling rate between the AFE5828ZAV and AFE5803ZCF?
The AFE5828ZAV integrates a 14-bit ADC with a maximum sampling rate of 65 MSPS. The AFE5803ZCF integrates a 14-bit ADC with a maximum sampling rate of 65 MSPS as well. Both target similar ultrasound signal-chain bandwidths, so selection depends on other system-level factors such as package, power, and channel density.
Do the AFE5828ZAV and AFE5803ZCF have the same power consumption?
They are not identical in power. The AFE5828ZAV is specified at approximately 158 mW per channel (typical), while the AFE5803ZCF is specified at approximately 101 mW per channel (typical). Designers should confirm the exact test conditions in the respective datasheets, since power scales with sampling rate and gain settings.
Can the AFE5828ZAV and AFE5803ZCF be used interchangeably in an existing PCB design?
No. The two devices use different packages (289-ball ZAV vs 135-ball ZCF), different ball maps, and different pin counts, so they are not footprint-compatible. A direct substitution would require a PCB redesign and full revalidation against the target system requirements.
What input signal range and LNA gain options do these AFEs support?
Both the AFE5828ZAV and AFE5803ZCF include a low-noise amplifier with selectable gain settings and a voltage-controlled attenuator for time-gain compensation in ultrasound receive chains. Exact LNA gain steps, input-referred noise, and attenuation range should be taken from the respective TI datasheets, as these parameters differ between the two parts.
Which device is better suited for lower-power portable ultrasound designs?
Based on published typical per-channel power, the AFE5803ZCF (approximately 101 mW per channel) consumes less power than the AFE5828ZAV (approximately 158 mW per channel), making the AFE5803ZCF generally more attractive for power-sensitive portable ultrasound systems, provided its package and channel configuration meet the design requirements.
