Replacement verdict
Compatible functional replacement candidate
The AFE5816ZAV and AFE5832ZBV are both Texas Instruments octal-channel ultrasound analog front ends sharing the same 289-ball NFBGA footprint and 1.8 V/3.3 V supply architecture, making the AFE5832ZBV a viable functional replacement candidate for the AFE5816ZAV in many ultrasound receive-chain designs. However, the two devices differ in ADC resolution, maximum sampling rate, and per-channel power consumption, so system-level validation of timing, SNR budget, and thermal performance is required before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AFE5816ZAV | AFE5832ZBV | Why it matters |
|---|---|---|---|
| Number of Channels | 16 | 32 | Channel count determines how many transducer elements or signal paths the AFE can support; a 32-channel device can serve twice the array size of a 16-channel device. |
| ADC Resolution | 14 bit | 12 bit | Higher ADC resolution provides greater dynamic range and finer quantization, which affects image quality and small-signal detection in ultrasound receive chains. |
| Maximum ADC Sampling Rate | 65 MSPS | 80 MSPS | Sampling rate sets the maximum signal bandwidth and Nyquist limit; a higher rate supports higher-frequency transducers and finer axial resolution. |
| LNA Gain Range | 12 dB to 30 dB | 12 dB to 30 dB | The low-noise amplifier gain range determines the sensitivity and noise figure trade-off for weak echo signals; matching ranges ease functional substitution. |
| Total Power Consumption | Approximately 1.1 W | Approximately 1.9 W | Power consumption affects thermal design, battery life, and system power budget, especially in portable ultrasound systems. |
| Package Type | NFBGA (ZAV) | NFBGA (ZBV) | Package footprint and pinout determine PCB layout compatibility; different packages typically require board redesign and are not drop-in substitutes. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | The industrial temperature range ensures reliable operation across environments; identical ranges simplify qualification for substitution. |
| Interface Type | LVDS serial output | LVDS serial output | The digital output interface must match the downstream FPGA or receiver; a common LVDS interface eases system integration. |

Frequently asked questions
What are the AFE5816ZAV and AFE5832ZBV?
The AFE5816ZAV and AFE5832ZBV are integrated analog front-end (AFE) devices from Texas Instruments intended for ultrasound and medical imaging signal chains. The AFE5816ZAV is an 8-channel AFE, while the AFE5832ZBV is a 32-channel AFE, both integrating a low-noise amplifier (LNA), voltage-controlled attenuator (VCA), programmable gain amplifier (PGA), and analog-to-digital converter (ADC) in a single package.
How do the channel counts of the AFE5816ZAV and AFE5832ZBV differ?
The AFE5816ZAV integrates 8 receive channels, whereas the AFE5832ZBV integrates 32 receive channels. This difference directly affects system channel density, PCB area, and the number of devices required to build a given ultrasound array front end.
Do the AFE5816ZAV and AFE5832ZBV use the same package type?
Both devices are offered in a ZAV/ZBV BGA-type package family from Texas Instruments, but the package body size and ball count differ because the AFE5832ZBV accommodates four times as many channels. PCB land patterns and thermal design must therefore be evaluated separately for each device.
What is the ADC resolution and sampling rate of these AFEs?
Both the AFE5816ZAV and AFE5832ZBV integrate 12-bit analog-to-digital converters. The maximum ADC sampling rate for each device should be confirmed against the respective Texas Instruments datasheet, as the specified maximum sample rate is a key parameter that differs between AFE variants and must be verified before design commit.
Can the AFE5816ZAV be used as a drop-in replacement for the AFE5832ZBV?
No. The two devices differ in channel count (8 versus 32), package size and ball count, power consumption, and digital output interface loading. A direct drop-in substitution is not possible; any migration requires a full schematic, layout, and firmware review against the Texas Instruments datasheets for both parts.
What digital output interface do the AFE5816ZAV and AFE5832ZBV provide?
Both devices provide serialized LVDS digital output for the ADC data. The exact number of LVDS lanes, lane rate, and framing format depend on the device configuration and must be verified in the respective Texas Instruments datasheet before interfacing with an FPGA or receiver.
How does power consumption compare between the AFE5816ZAV and AFE5832ZBV?
Per-channel power is the relevant comparison metric, since the AFE5832ZBV integrates four times as many channels as the AFE5816ZAV. Total device power scales with channel count and configured sampling rate; designers should use the per-channel power figures published in the Texas Instruments datasheets to estimate system-level thermal budgets.
What are the typical applications for these AFE devices?
Both the AFE5816ZAV and AFE5832ZBV are intended for medical ultrasound imaging systems and similar multi-channel receive architectures requiring low-noise amplification, time-gain compensation, and digitization. The higher channel count of the AFE5832ZBV suits high-density array probes, while the AFE5816ZAV suits lower-channel-count or space-constrained designs.
