MAX19528EXE+T Overview
An ADC (analog-to-digital converter) is an integrated circuit that converts continuous analog signals into discrete digital codes, enabling real-world analog phenomena to be processed by digital signal processors, FPGAs, and microcontrollers. Multi-channel, high-speed ADCs like the MAX19528 sit within the broader data acquisition and signal chain hierarchy: ADC -> data converter -> data acquisition IC -> mixed-signal semiconductor. They are commonly paired with operational amplifiers for input buffering, voltage references for absolute accuracy, and clock generators for sample timing.
Key features include 12-bit native resolution, eight simultaneous-sampling input channels, 64 MSPS maximum sampling rate, a serial output interface that reduces pin count versus parallel ADCs, and a compact 144-pin CTBGA package measuring roughly 12 mm x 12 mm. The combination of channel density and sample rate makes the part particularly suited for imaging, ultrasound, communications baseband, and multi-phase motor control front-ends.
The device integrates an internal reference and input track-and-hold amplifiers per channel, simplifying the external analog front end. Designers should observe the datasheet's recommended layout for the exposed paddle beneath the CTBGA, which serves as the primary thermal and ground return path and must be soldered to a continuous ground plane for ADC noise performance.
Typical applications include medical imaging receivers, multi-channel baseband digitizers in software-defined radio, ultrasound beam-forming front-ends, industrial process control and instrumentation, and radar / phased-array intermediate-frequency sampling.
When designing with this ADC, prioritize a low-noise ground plane and short, matched analog input traces. Decouple AVDD with 0.1 uF ceramic capacitors placed as close to the supply pins as possible, and keep digital output traces away from analog input traces to minimize digital coupling into the sampling network.

Typical Applications
MAX19528EXE+T is suitable for 7 applications: Medical Ultrasound Beam-Forming Front-End, Multi-Channel Software-Defined Radio Baseband, Phased-Array Radar IF Sampling, Multi-Phase Motor Control & Inverter Feedback, Industrial Process Control Data Acquisition, Multi-Channel Vibration & Acoustic Monitoring, Multi-Antenna MIMO Receiver Digitizer.
Medical Ultrasound Beam-Forming Front-End
The MAX19528EXE+T's 8-channel input mux and 64 MSPS sampling rate let one IC digitize an entire 8-element transducer array for portable ultrasound. With internal reference and serial LVDS output, the part keeps the analog front-end dense and the digital trace count low, which is critical for handheld probes where PCB area is measured in square centimeters and channel-to-channel gain matching determines beam-steering accuracy.
Recommended
Multi-Channel Software-Defined Radio Baseband
In SDR baseband receivers, the MAX19528EXE+T digitizes up to eight I/Q or intermediate-frequency channels at 64 MSPS, well above the Nyquist rate for sub-30 MHz IF signals. The 12-bit resolution combined with the integrated input mux allows direct connection to multiple mixers, eliminating external analog switches and reducing LO leakage that would otherwise degrade receiver sensitivity.
Recommended
Phased-Array Radar IF Sampling
Phased-array radar modules require sampling many IF channels with tight gain and phase matching. The MAX19528EXE+T provides 8 matched channels on one die, eliminating the channel-mismatch error that plagues discrete ADC designs. The serial output interface also minimizes PCB trace congestion behind the antenna array, where every saved millimeter of trace length preserves beam-pointing accuracy at microwave frequencies.
Recommended
Multi-Phase Motor Control & Inverter Feedback
Three-phase motor inverters need at least three current/voltage feedback channels; the MAX19528EXE+T's 8 channels allow simultaneous sensing of all three phase currents plus DC-bus voltage and temperature - all on a single ADC. The 64 MSPS sample rate comfortably exceeds the PWM carrier bandwidth, enabling closed-loop control bandwidths well above 50 kHz without aliasing the current ripple into the torque loop.
Recommended
Industrial Process Control Data Acquisition
Process-control PLCs and distributed I/O subsystems use the MAX19528EXE+T to digitize up to eight 4-20 mA or 0-10 V analog inputs simultaneously. The 12-bit resolution provides 0.024% full-scale step size - adequate for valve-position feedback and pressure-transducer readback - while the serial output interface allows the ADC to be located directly at the analog terminal block, eliminating long analog trace runs that pick up plant-noise interference.
Recommended
Multi-Channel Vibration & Acoustic Monitoring
Structural-health monitoring systems place MEMS accelerometers at multiple points on a bridge, turbine, or machine frame; the MAX19528EXE+T aggregates up to eight piezo channels at 64 MSPS. The 12-bit dynamic range comfortably captures the broadband vibration spectra above 20 kHz, while the 144-CTBGA package enables compact mounting directly on the sensor PCB to keep accelerometer cable runs short.
Recommended
Multi-Antenna MIMO Receiver Digitizer
5G and Wi-Fi 6E MIMO radios use 4-8 antennas, each with its own baseband chain. The MAX19528EXE+T digitizes up to eight baseband I/Q channels at 64 MSPS - ideal for sub-6 GHz radios whose channel bandwidths stay below 20 MHz. The serial LVDS interface reduces the digital pin count versus parallel ADCs, which is critical when routing 8 channels into a small baseband FPGA.

Design Notes
Solder the exposed paddle beneath the 144-CTBGA directly to a continuous, unbroken ground plane. The paddle is the primary low-impedance return for all eight ADC channels; any slot or trace cut beneath the package will inject switching noise into the analog front end and degrade SNR by several dB. Use 0.1 uF X7R ceramic decoupling capacitors within 2 mm of every AVDD and DVDD pin, with a 10 uF bulk tantalum or ceramic capacitor on each supply rail placed within 10 mm of the package.
Route the eight analog input traces as a matched-length, matched-impedance bundle (typically 50 ohm single-ended or 100 ohm differential). Keep these traces on the top layer over an unbroken analog ground pour, and place a digital ground pour on an adjacent layer separated by at least 0.2 mm of dielectric. Avoid routing any digital output trace within 3 mm of an analog input trace to minimize capacitive coupling into the sampling network.
Source the ADC sample clock from a low-jitter crystal oscillator or clock conditioner (jitter below 5 ps RMS) and keep the clock trace length matched across all channels. According to the Maxim datasheet, the analog input bandwidth and SNR are directly limited by sample-clock jitter at high input frequencies; at 30 MHz analog input, 5 ps of jitter already consumes 1 LSB of the 12-bit code at 64 MSPS.
Do not assume simultaneous sampling across all 8 channels: the MAX19528EXE+T uses an internal input multiplexer feeding one conversion core, so channels are sampled sequentially. For applications requiring true simultaneous sampling (e.g., phased-array radar), use the MAX19528 only after verifying timing in the datasheet, or select a true simultaneous-sampling ADC family such as the MAX19775 instead.
Estimated: at full 64 MSPS operation across 8 channels with AVDD = 3.3 V, the MAX19528EXE+T dissipates approximately 0.5 W of heat into the 144-CTBGA's exposed paddle. The CTBGA's theta_JA of roughly 25 C/W (with proper paddle soldering) yields a junction-to-ambient rise of about 12 C; this is well within the part's thermal limits and no external heatsink is required, but adequate airflow is recommended in enclosed enclosures.
Compliance Information
RoHS and lead-free compliance per distributor listings (DigiKey, Mouser). Reach and conflict-minerals compliance inferred from Maxim Integrated / Analog Devices corporate policy. AEC-Q100 is not applicable since this is an industrial/medical-grade ADC, not an automotive-grade part.
