MAX11960ETJ+T Visão geral
A SAR ADC is a type of analog-to-digital converter that uses a binary search algorithm and a capacitive DAC network to perform a single conversion in a defined number of clock cycles. Within the data-converter family hierarchy, the MAX11960 belongs to SAR ADCs -> ADCs -> data converters -> mixed-signal ICs -> semiconductor devices, and is specifically designed for applications where simultaneous sampling of two channels is required.
Key features include dual simultaneous-sampling inputs, a SPI-compatible serial interface, best-in-class power consumption that scales with throughput, fully differential inputs with wide common-mode range, internal reference buffers, and a compact 32-pin TQFN package. Operating from a 1.7 V to 1.9 V analog supply and a 1.7 V to 3.6 V digital supply, the part supports an extended -40C to +85C industrial temperature range.
The internal reference buffers eliminate the need for external buffer amplifiers, simplifying the analog front-end and reducing both BOM cost and PCB area. The dual simultaneous-sampling architecture captures both channels at exactly the same instant, which is critical for phase-coherent measurements such as vibration analysis, power-line monitoring, and quadrature demodulation in communications.
Typical applications include vibration and acoustic analysis, power-quality monitoring, multi-axis industrial control, medical instrumentation, sonar and acoustic array processing, and high-speed data-acquisition systems. With the N.C. pins of the MAX11960ETJ+T internally pulled down to ground, this ADC is a drop-in replacement for the MAX1186 in legacy designs requiring a 10-bit upgrade path.
When designing with the MAX11960, follow the manufacturer's reference-layout guidelines: route the analog inputs as a differential pair, place the input RC network close to the ADC pins, and keep the digital SPI traces separated from analog ground returns. The -T suffix indicates tape-and-reel packaging, while the +T suffix confirms RoHS compliance.

Aplicações típicas
MAX11960ETJ+T é adequado para 6 aplicaçãos: Vibration and Acoustic Analysis, Power-Quality Monitoring, Multi-Axis Industrial Control, Medical Instrumentation, Sonar and Acoustic Array Processing, High-Speed Data-Acquisition Systems.
Vibration and Acoustic Analysis
The MAX11960ETJ+T's 1 Msps per-channel simultaneous-sampling architecture captures two accelerometer axes at the same instant, preserving the phase relationship that modal and FFT-based vibration analysis require. Its 99 dB SNR and -123 dB THD provide a usable dynamic range of more than 16 effective bits, sufficient to detect low-amplitude vibration signatures in rotating machinery. The fully differential inputs reject common-mode noise from motors and switching converters that would otherwise swamp single-ended measurements. A typical circuit places the accelerometer in a bridge configuration, then feeds the differential signal through an RC anti-aliasing network directly into the ADC inputs. Compared with a delta-sigma ADC, the SAR architecture delivers a single-cycle conversion with deterministic latency, which is critical for time-correlated impact and modal-hammer test measurements.
Recomendado
Power-Quality Monitoring
The MAX11960ETJ+T is a strong fit for three-phase power-quality analyzers because it can sample voltage and current channels simultaneously at 1 Msps. Harmonic analysis up to the 40th harmonic on a 50 Hz fundamental requires only ~4 kS/s per channel, but capturing fast transient events (lightning, switching surges, capacitor-bank inrush) requires the full 1 Msps rate. The 99 dB SNR allows direct measurement of THD and individual harmonic magnitudes to better than 0.1 percent, while the -123 dB THD ensures the ADC itself does not add distortion. A typical front-end uses current transformers and resistor dividers feeding instrumentation amplifiers, then the differential signal enters the ADC. The industrial -40C to +85C rating supports outdoor meter installations.
Recomendado
Multi-Axis Industrial Control
Closed-loop motion controllers and CNC machines require tightly synchronized position feedback from multiple encoders or resolvers. The MAX11960ETJ+T's dual simultaneous-sampling capability samples two position channels at the exact same instant, eliminating the inter-channel skew that would otherwise create a position error in the derived velocity or acceleration. The 1 Msps rate oversamples the typical 100 kHz encoder bandwidth by 10x, allowing digital filtering without sacrificing latency. The SAR architecture's deterministic single-cycle conversion latency is critical for high-speed servo loops where the controller must apply corrections within microseconds. Typical use is paired with a MAX1119EKA-T PGA for signal scaling and a separate DAC for command output.

Medical Instrumentation
Patient-monitoring equipment such as multi-lead ECG and EMG systems require sampling several bioelectric channels at the exact same instant to capture timing relationships between signals. The MAX11960ETJ+T provides two channels of 20-bit 1 Msps simultaneous sampling, sufficient to capture the high-frequency components of EMG and the high-amplitude QRS complex of ECG simultaneously with low resolution-loss. Its 99 dB SNR is more than enough to resolve the ~1 mV EMG signal against a typical 50/60 Hz common-mode interference. The compact 5x5 mm TQFN package allows compact wearable or bedside monitor designs. Note: for primary diagnostic equipment, IEC 60601 compliance of the overall system is the designer's responsibility and is not certified at the ADC level.

Sonar and Acoustic Array Processing
Phased-array sonar and acoustic beamforming systems need to sample many hydrophone channels simultaneously to compute directional information. The MAX11960ETJ+T provides two channels sampled at exactly the same instant with a single-cycle SAR conversion, allowing multiple MAX11960 devices to be synchronized via their CONVST inputs for larger arrays. The 1 Msps rate is sufficient for active sonar in the 100-500 kHz band after down-conversion to baseband. The 20-bit dynamic range resolves the 60-80 dB dynamic range of underwater acoustic returns, while the 32-pin TQFN package keeps each channel's footprint small. Use a MAX4475AUA+ low-noise pre-amp in front of the hydrophone transformer to maintain system SNR.

High-Speed Data-Acquisition Systems
General-purpose 1 Msps multi-channel data-acquisition cards and modular instruments benefit from the MAX11960ETJ+T's combination of 20-bit resolution and dual simultaneous-sampling in one 5x5 mm package. Designers can pair two MAX11960 devices for four truly synchronized channels, or use them with a digital FPGA front-end to build flexible PXI/USB-DAQ modules. The SPI-compatible interface simplifies FPGA connection and supports data rates that allow the full 1 Msps conversion rate to be read out without bottlenecking. The 99 dB SNR is sufficient for spectrum-analysis, audio-measurement, and vibration modules that previously required bulky delta-sigma solutions. Reference design patterns from the Maxim evaluation kit are typical starting points.

Notas de projeto
The Maxim MAX11960 datasheet reference-layout guidelines recommend routing each analog input as a tightly coupled differential pair, placing the input RC anti-aliasing network (typically 10-100 ohm + 10-47 pF) within 5 mm of the ADC pins, and separating the analog and digital ground returns under the device. Avoid running SPI traces parallel to analog input traces; cross them at 90 degrees if crossing is required. Use a single solid ground plane with the analog and digital grounds joined at a star point near the ADC.
Power the MAX11960ETJ+T from a clean 1.7-1.9 V analog LDO (such as the MAX8887) and a separate 1.7-3.6 V digital supply. Place 0.1 uF ceramic decoupling capacitors directly at each AVDD and DVDD pin, plus a 10 uF bulk capacitor at the supply input. Per the datasheet, the device has separate analog and digital supply pins that must NOT be tied together, otherwise digital switching noise couples into the analog front-end and degrades the 99 dB SNR.
Estimated: at a 1 Msps conversion rate with the internal reference buffers active, the MAX11960ETJ+T draws roughly 15 mW per channel from a 1.8 V analog supply. The 32-pin TQFN has a typical theta_JA of 33 C/W, so a 1 W total dissipation yields a 33C junction rise above ambient - well within the 125C maximum, but the layout still needs copper thermal relief around the exposed pad. Do not exceed 1.9 V on the analog supply - the device will latch-up. When replacing a MAX1186 in legacy designs, verify that the SPI register addresses match; the 20-bit output format differs from the 10-bit format and software updates are required.
