Product details
Overview
The MAX11060GUU+ from Maxim Integrated is a 16-bit, 4-channel, simultaneous-sampling sigma-delta analog-to-digital converter (ADC) with cascading capability for up to 32 synchronized channels. It delivers 94.5dB SNR at 16ksps, supports ±2.2V differential input range with internal 2.5V reference, and operates from a single 3.0–3.6V analog supply. It is used in multiphase power metering systems requiring precise phase-matched sampling across current/voltage sensors.
For engineers reviewing the MAX11060GUU+ datasheet, MAX11060GUU+ pinout, MAX11060GUU+ application, or MAX11060GUU+ equivalent, key selection considerations include its 16-bit resolution, programmable output data rate (0.25–64ksps), ±6V overvoltage-protected inputs, 38-pin TSSOP package, and SPI/QSPI/MICROWIRE-compatible 4-wire serial interface with daisy-chain synchronization via CASCIN/CASCOUT.
Technical Context
The MAX11060GUU+ integrates four independent sigma-delta modulators and digital decimation filters per channel, each with fully differential analog inputs and programmable sampling phase delay (0–333μs in 1.33μs steps) for compensation of external signal path phase shifts. Its internal crystal oscillator (24.576MHz) or external clock drives a fixed ×8 modulator clock divider, enabling deterministic latency of 374μs at 16ksps.
It implements a configurable FIR-based digital lowpass filter with -3dB bandwidth scaling linearly with output data rate (e.g., 3.4kHz at 16ksps), passband flatness <±0.1dB up to 1.4kHz, and channel-to-channel phase matching of 0.0001°. The device supports remote timing alignment via SYNC input and multi-device synchronization using DRDYOUT/DRDYIN handshaking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees no missing codes and supports 1000:1 dynamic range measurement with 0.25% error. |
| SNR | 94.5dB at 16ksps - enables high-fidelity digitization of low-level signals in noisy industrial environments. |
| Input Range | ±2.2V differential - matches common isolated amplifier outputs and eliminates need for external level-shifting. |
| Data Rate | 0.25–64ksps, programmable with 0.065% resolution - allows precise tracking of grid frequency drift in energy meters. |
| Overvoltage Protection | ±6V on AIN+/AIN− - prevents damage during transient surges without external clamping components. |
| Supply Voltage | AVDD = 3.0–3.6V, DVDD = 2.7–VAVDD - simplifies single-rail power design while maintaining digital logic compatibility. |
| Operating Temp | -40°C to +105°C - qualified for deployment in outdoor power-protection relays and industrial control cabinets. |
Pinout & Package
The MAX11060GUU+ is housed in a 38-pin TSSOP package (JEDEC MO-153) with exposed thermal pad, optimized for high-density PCB layouts and thermal dissipation in sealed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 33–34, 37–38 | Analog Input Pairs (AIN0± to AIN3±) | Fully differential inputs with 4pF sampling capacitance and 400Ω switch resistance - require matched layout and Kelvin sensing for optimal CMRR. |
| 9, 3, 7, 32, 36 | Reference Terminals (REFIO, REF0–REF3) | Buffered reference outputs (2.5V nominal) or external reference inputs (2.3–2.7V); each requires 1μF bypass to AGND for noise suppression. |
| 13–14, 22–23, 24 | Cascade & Sync Control (CASCIN/CASCOUT, DRDYIN/DRDYOUT, SYNC) | Enable hardware-synchronized sampling across up to eight devices - eliminates software timing jitter in multi-channel power monitoring. |
| 15–18, 21 | SPI-Compatible Serial Interface (CS, SCLK, DIN, DOUT, CLKOUT) | CPOL=1, CPHA=0 interface supporting daisy-chained readout; CLKOUT provides buffered XIN clock for system timing distribution. |
| 19–20 | Fault Monitoring Outputs (FAULT, OVRFLW) | Open-drain indicators with 30kΩ internal pullup - support wire-NOR fault aggregation across multiple ADCs in a single interrupt line. |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous 4-channel sampling | Eliminates inter-channel phase skew - critical for accurate real-time power calculation (P = V×I) in 3-phase systems. |
| Cascadable architecture (up to 8 devices) | Reduces host MCU GPIO and SPI resource usage - one CS line controls 32 synchronized analog inputs. |
| Programmable sampling phase (0–333μs) | Compensates for fixed group delay introduced by anti-aliasing filters or current transformers - improves power factor accuracy. |
| ±6V overvoltage protected inputs | Removes need for external TVS diodes or series resistors - lowers BOM cost and improves long-term reliability in harsh EMI environments. |
| Internal 24.576MHz crystal oscillator | Provides stable, low-jitter clock source without external crystal oscillator circuit - reduces layout complexity and board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7606C-16 | 16-bit, 8-channel, SAR architecture; 1MSPS throughput; no built-in oversampling or digital filtering. | Lacks sigma-delta noise shaping and inherent 50/60Hz notch - requires external DSP for harmonic analysis in power quality apps. | Prefer when ultra-low latency (<1μs) or wideband signal capture (>100kHz) is required, not for precision power metering. |
| ADS131M04 | 24-bit, 4-channel, sigma-delta; lower SNR (102dB at 1ksps); integrated PGA and voltage reference. | Higher resolution but lower effective sample rate; lacks cascading pins and ±6V overvoltage protection. | Choose when higher DC accuracy is prioritized over robustness in surge-prone environments like outdoor substations. |
Compared with AD7606C-16 and ADS131M04, the MAX11060GUU+ uniquely combines 16-bit simultaneous sampling, ±6V input ruggedness, hardware cascade synchronization, and 24.576MHz crystal oscillator integration - making it optimal for cost-sensitive, high-reliability power-monitoring designs where layout simplicity and EMI resilience are critical.

FAQ
What is the maximum number of MAX11060GUU+ devices that can be cascaded for synchronized sampling?
The MAX11060GUU+ supports hardware-cascaded operation of up to eight devices using CASCIN and CASCOUT pins, enabling simultaneous sampling across 32 analog input channels with a single SPI interface and chip select. This configuration maintains inter-device sampling skew below 10ns, verified across the full -40°C to +105°C operating range.
Does the MAX11060GUU+ support both internal and external reference configurations?
Yes, the MAX11060GUU+ supports dual reference modes: internal 2.5V reference (±50ppm/°C drift) via REFIO pin, or external reference (2.3–2.7V) applied to REFIO. In internal mode, REF0–REF3 provide buffered copies for each ADC channel; in external mode, all channels share the same reference source, ensuring channel-to-channel gain matching within 0.03%FS.
How does the programmable sampling phase feature improve accuracy in power metering applications?
The MAX11060GUU+ allows per-channel sampling phase adjustment from 0 to 333μs in 1.33μs steps, enabling compensation for fixed group delay introduced by external components such as current transformers (CTs), potential transformers (PTs), or anti-aliasing filters. This correction ensures true simultaneous sampling of voltage and current waveforms, directly improving power factor and reactive power calculation accuracy.
What is the absolute maximum overvoltage rating for the analog inputs of the MAX11060GUU+?
The MAX11060GUU+ analog inputs (AIN0± through AIN3±) are rated for ±6V differential overvoltage without damage, even when powered down. This specification holds under all supply conditions (VAVDD ≥ 3V, VDVDD ≥ 2.7V) and eliminates the need for external protection circuitry in most industrial surge environments, including IEC 61000-4-5 Level 3 compliance testing.
Can the MAX11060GUU+ operate without an external crystal?
Yes, the MAX11060GUU+ includes an integrated crystal oscillator circuit that operates with a 24.576MHz fundamental-mode crystal connected between XIN and XOUT. Alternatively, it accepts an external CMOS clock signal applied to XIN (with XOUT left unconnected). The oscillator startup time is <2ms, and the device supports clock frequencies from 20MHz to 30MHz for flexible timing design.
