MAX1060BEEI+T Visão geral
A successive-approximation register (SAR) ADC is a type of data converter that converts an analog input signal into a digital code by iteratively approximating the input voltage against an internal digital-to-analog converter (DAC). SAR ADCs are favored in industrial and instrumentation designs because they offer deterministic latency, no pipeline delay, and excellent DC accuracy at sample rates up to several Msps. The MAX1060 belongs to the SAR ADC -> ADC -> data converter -> mixed-signal IC hierarchy, and within Maxim's portfolio it shares a common architecture with the MAX1062/MAX1063 family.
Key features include a true-differential analog input track-and-hold amplifier with 4 MHz full-power bandwidth, an internal +2.5V reference with 50 ppm/°C typical drift, software-configurable unipolar (0 to VREF) or bipolar (±VREF/2) input ranges, and a single +5V analog supply requirement. The integrated reference eliminates the need for an external precision reference, which reduces BOM cost and board area in multi-channel data-acquisition systems.
The MAX1060 is typically used in industrial process control, portable instrumentation, and data-logging designs that need simultaneous-sampling-free multichannel conversion with deterministic throughput. Its 400 ksps throughput and 8 single-ended input channels make it suitable for digitizing sensor arrays, multiplexer-front-ended measurement systems, and embedded control loops.
When designing with this part, place the supply bypass capacitors as close as possible to the AVDD and DVDD pins and avoid routing digital signals across the analog input traces. The internal reference output (REF) requires a 4.7 uF bypass capacitor for specified noise performance; using a smaller value will degrade SNR. Do not operate below 4.75V without consulting the manufacturer's datasheet because the internal reference regulation may be compromised.

Aplicações típicas
MAX1060BEEI+T é adequado para 6 aplicaçãos: Industrial Process Control Data Acquisition, Portable Battery-Powered Instrumentation, Multi-Channel Sensor Array Digitization, Motor Control Feedback Loops, Medical Patient Monitoring Equipment, Data Logging and Embedded Recording Systems.
Industrial Process Control Data Acquisition
The MAX1060BEEI+T is well matched to industrial process control because its 8 single-ended input channels accept multiple sensor signals (4-20 mA transduced, RTD, or thermocouple amplifier outputs) sequentially at 400 ksps aggregate throughput. The internal +2.5 V reference eliminates the need for a precision external reference, reducing BOM cost and PC board area in PLC analog input modules. Its -40 °C to +85 °C industrial temperature rating supports factory-floor enclosures, and the parallel interface allows a host microcontroller or FPGA to read conversion results with deterministic timing in real-time control loops.
Recomendado
Portable Battery-Powered Instrumentation
The MAX1060BEEI+T fits portable battery-powered instrumentation because its power-down mode drops supply current below 10 uA, extending battery life between measurement bursts. Operating from a single +5V supply, the part is suitable for handheld multimeters, portable environmental loggers, and field-test instruments that digitize multiple analog channels sequentially. The integrated +2.5V reference saves PCB area in compact handheld enclosures, while the SSOP-28 footprint allows routing on 2-layer boards. A typical design wakes the ADC on demand, performs a burst conversion, and returns to power-down between samples.
Recomendado
Multi-Channel Sensor Array Digitization
For sensor array digitization, the MAX1060BEEI+T offers 8 single-ended or 4 true-differential inputs that can be software-routed to the internal SAR core. This architecture suits strain-gauge bridges, thermistor arrays, and optical sensor front-ends where multiple analog channels must be sampled deterministically. The 400 ksps aggregate throughput allows sequential sampling of up to 8 channels at 50 ksps each, sufficient for vibration analysis and multi-axis force measurement systems. Differential input mode cancels common-mode noise in long sensor cables, improving SNR in electrically noisy industrial environments.
Recomendado
Motor Control Feedback Loops
In brushless DC and stepper motor control loops, the MAX1060BEEI+T digitizes current-sense amplifier outputs and potentiometer position feedback at 400 ksps aggregate, enabling sub-100 us control loop updates. The deterministic SAR latency (no pipeline delay) simplifies software compensation in field-oriented control algorithms running on companion microcontrollers. Its 8-channel capacity handles 3-phase current sensing plus auxiliary voltage and temperature channels in a single ADC, reducing PCB area in servo drive modules compared to multi-ADC designs.
Recomendado
Medical Patient Monitoring Equipment
The MAX1060BEEI+T supports medical patient monitoring where multiple physiological signals (temperature, SpO2 analog front-end output, respiration impedance) require simultaneous digitization. Its internal +2.5V reference provides stable conversion accuracy over time and temperature, which is critical for diagnostic-grade measurements. The parallel interface allows direct connection to medical-grade microcontrollers, while the -40 °C to +85 °C operating range supports equipment used in varied clinical environments. Differential input mode rejects common-mode interference from power-line coupling on patient cables.
Recomendado
Data Logging and Embedded Recording Systems
Embedded data loggers use the MAX1060BEEI+T to digitize multiple analog channels from environmental sensors (humidity, pressure, gas concentration transducers) at scheduled intervals. The 400 ksps throughput supports high-speed transient capture for shock and vibration recorders, while the power-down mode reduces average consumption to microamp levels between samples for multi-year battery life. The 28-pin SSOP package enables compact PCB designs suitable for wearable and IoT data loggers, and the parallel interface allows direct bus attachment to low-cost microcontrollers without SPI overhead.

Principais diferenciais
- Integrated +2.5V reference with 4.7 uF bypass only (vs MAX1060BCEE+T)
- Highest channel count in the family (vs MAX1062BCEE+T)
- Single +5V supply operation simplifies power design (vs MAX1061EEI+T)
Notas de projeto
Place a 10 uF tantalum or ceramic bypass capacitor directly at the AVDD pin and a 0.1 uF ceramic capacitor at the DVDD pin, both with traces shorter than 5 mm to the IC. The MAX1060BEEI+T draws up to 1.9 mA during conversion; an undersized supply capacitor can cause AVDD droop that injects reference noise into the conversion result. Star-ground AGND and DGND at a single point near the IC to avoid digital switching currents corrupting analog ground.
Do not omit the 4.7 uF bypass capacitor on the REF pin - the MAX1060BEEI+T's internal +2.5 V reference requires this capacitor to meet its noise specification. Using a smaller value (e.g. 0.1 uF) will reduce SNR and may cause conversion instability. Also, do not drive the analog inputs beyond AVDD + 0.3 V or below AGND - 0.3 V; the internal ESD diodes will forward-bias and corrupt the conversion or damage the input stage.
Route analog input traces (AIN0-AIN7) as differential pairs with constant impedance and avoid crossing them with digital output bus traces (D0-D7, EOC, CNVST). Keep digital output traces short or series-terminate with 33 ohm resistors to suppress reflections that could couple into sensitive analog inputs. Place the REF bypass capacitor immediately adjacent to the REF pin with a via to the analog ground plane within 2 mm to minimize reference noise coupling.
When using the parallel interface at high conversion rates (>200 ksps aggregate), insert 33-47 ohm series resistors at the D0-D7 digital outputs to dampen transmission-line reflections on the bus connecting to the host microcontroller. The parallel bus switching can inject switching noise into AVDD; consider adding a small ferrite bead between the digital supply rail and the DVDD pin to isolate high-frequency digital noise.
