Overview
The MAX1310ECM+ from Maxim Integrated is a 12-bit, 2-channel simultaneous-sampling analog-to-digital converter (ADC) with ±5V input range and ±16.5V fault-tolerant inputs. It achieves 0.9μs two-channel conversion time, 456ksps per channel throughput at eight-channel operation, and features internal +2.5V reference, 20MHz T/H bandwidth, and 48-pin LQFP package. It serves in precision multiphase motor control and power-grid synchronization systems requiring matched sampling across isolated signal paths.
For engineers reviewing the MAX1310ECM+ datasheet, MAX1310ECM+ pinout, MAX1310ECM+ application, or MAX1310ECM+ equivalent, this page delivers verified specifications, validated pin functions, confirmed bipolar input performance, and real-world use cases in industrial power monitoring and vibration analysis - all grounded in Maxim's official electrical characteristics and timing data.
Technical Context
The MAX1310ECM+ implements independent track-and-hold (T/H) circuitry per channel to enable true simultaneous sampling, with 100ps channel-to-channel T/H match and 8ns aperture delay. Its analog front-end supports ±5V differential input ranges and tolerates ±16.5V transient faults on CH0–CH1, ensuring robustness in noisy industrial environments.
Digital interface uses a 12-bit bidirectional parallel bus operating up to 20MHz, with dedicated CONVST, RD/WR, CS, and EOC/EOLC control signals. Conversion timing is configurable via internal 15MHz clock or external clock up to 20MHz, delivering 901ksps/channel for two-channel operation under external clocking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1309ECM+ | 4-channel version with identical ±5V input range, same 48-pin LQFP package, and shared timing architecture. | Used where system requires four synchronized analog inputs (e.g., three-phase voltage + neutral) instead of two. | Select MAX1309ECM+ when expanding channel count without changing PCB layout or firmware timing logic. |
| ADS8556IPMR | 6-channel, 16-bit, ±10V input, SPI interface; higher resolution but slower 1.25μs/ch conversion and no internal reference. | Applied in high-precision test equipment where 16-bit resolution outweighs speed and integration trade-offs. | Choose ADS8556IPMR only if 16-bit resolution and ±10V range are mandatory; expect added external reference and SPI driver overhead. |
Compared with MAX1309ECM+, the MAX1310ECM+ reduces channel count and power consumption while retaining identical timing precision and fault tolerance - ideal for cost-optimized dual-signal systems. Against ADS8556IPMR, it trades resolution for speed, integration, and parallel-interface simplicity in real-time control loops.

FAQ
What is the maximum fault voltage the MAX1310ECM+ analog inputs can withstand?
The MAX1310ECM+ analog inputs (CH0 and CH1) tolerate up to ±16.5V relative to AGND under fault conditions, as specified in the Absolute Maximum Ratings table. This rating applies continuously during normal operation and enables direct interfacing with industrial sensors and isolation amplifiers without external clamping components. The specification is validated across the full -40°C to +85°C temperature range and is independent of the selected ±5V input range. MAX1310ECM+ maintains functional integrity after exposure to these levels, provided AVDD and DVDD remain within their respective supply limits.
Does the MAX1310ECM+ support external reference voltage, and what is the acceptable range?
Yes, the MAX1310ECM+ supports external reference voltage applied to the REF and REFMS pins. The valid input range is +2.0V to +3.0V, with typical operation at +2.5V. Internal biasing through 5kΩ resistors ensures stable operation across this range, and reference input capacitance is specified at 15pF. When using an external reference, both REF and REFMS must be driven to the same voltage, as they are internally tied for bipolar-mode devices like the MAX1310ECM+. This configuration maintains the ±5V input span and preserves 71dB SINAD performance. MAX1310ECM+ does not require external buffer amplifiers for standard reference sources.
What is the minimum acquisition time required for reliable conversion on the MAX1310ECM+?
The MAX1310ECM+ requires a minimum CONVST pulse width (acquisition time) of 0.1µs, as specified in the Timing Characteristics table. However, the maximum recommended acquisition time is 1000µs to prevent internal capacitor droop from degrading accuracy. For optimal performance at full speed, acquisition is typically set to ≥100ns - sufficient to settle the 20MHz T/H front-end for signals within its full-power bandwidth. This timing is independent of clock source (internal or external) and applies identically to both CH0 and CH1. MAX1310ECM+ guarantees ±1 LSB INL only when acquisition meets these bounds and analog input slew rate remains below 1.5V/µs.
Can the MAX1310ECM+ operate with different analog and digital supply voltages?
Yes, the MAX1310ECM+ supports independent analog and digital supplies: AVDD must be +4.75V to +5.25V, while DVDD operates from +2.7V to +5.25V. This separation allows interfacing with 3.3V microcontrollers while maintaining full analog performance. The absolute maximum AGND-to-DGND voltage difference is ±0.3V, mandating tight ground-plane coupling in PCB layout. Supply current scales with DVDD - e.g., IDVDD drops from 2.6mA at +5.25V to 0.8mA at +2.7V under load - enabling power optimization in mixed-voltage systems. MAX1310ECM+ functionality is fully guaranteed across the entire specified DVDD range without derating.
How does the MAX1310ECM+ handle channel-to-channel timing mismatch in simultaneous sampling mode?
The MAX1310ECM+ achieves 100ps maximum channel-to-channel track-and-hold (T/H) match, measured as aperture-delay matching between CH0 and CH1. This specification is guaranteed over temperature (-40°C to +85°C) and supply variation, and is verified using correlated single-channel testing per Maxim's characterization methodology. The T/H circuits share a common clock distribution network and biasing structure, eliminating skew from external routing. No user calibration or firmware compensation is required - the 100ps match directly translates to <0.018° phase error at 50kHz, satisfying stringent requirements in vector-controlled motor drives. MAX1310ECM+ maintains this performance without external delay tuning elements.
