Product details
Overview
The MAX11160EUB+T from Maxim Integrated is a 16-bit, 500ksps successive-approximation register (SAR) analog-to-digital converter with integrated 5ppm/°C internal reference, single 5V analog supply operation, and SPI-compatible serial interface supporting 2.5V–5V logic levels; it delivers 92.5dB SINAD and –105dB THD at 20kHz for precision measurement in industrial sensor interfaces and data acquisition systems.
For engineers reviewing the MAX11160EUB+T datasheet, MAX11160EUB+T pinout, MAX11160EUB+T application, or MAX11160EUB+T equivalent, key selection considerations include internal reference drift performance, pseudo-differential input range (0V to VREF, VREF ≤ VDD), zero-latency conversion, and compatibility with µMAX-10 package layout constraints.
Technical Context
The MAX11160EUB+T implements a true SAR architecture with no pipeline delay, enabling deterministic timing for real-time control loops. It uses an internal bandgap reference trimmed to 5ppm/°C drift over –40°C to +85°C, eliminating external reference components while maintaining 16-bit monotonicity and no missing codes.
Its pseudo-differential input stage accepts 0V to VREF signals with VREF programmable up to VDD (5V), and the SPI/QSPI/MICROWIRE®-compatible serial interface operates across 2.3V–5V digital supply range, supporting direct interfacing to FPGA, microcontroller, or DSP host logic without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with guaranteed no missing codes - ensures full code coverage for high-fidelity signal capture. |
| Sampling Rate | 500ksps - supports Nyquist-limited bandwidth up to 250kHz for anti-aliasing filter design. |
| SINAD | 92.5dB at 20kHz - enables >15.3 effective number of bits (ENOB) in audio and sensor bandwidths. |
| THD | –105dB at 20kHz - minimizes harmonic distortion in precision instrumentation applications. |
| Reference Drift | 5ppm/°C - reduces system-level calibration frequency in temperature-varying environments. |
| Power Dissipation | 34mW at 500ksps; 1µA in shutdown - enables low-power portable or battery-backed DAQ designs. |
| Digital Supply Range | 2.3V to 5V - allows direct connection to mixed-voltage SoC or MCU I/O domains. |
Pinout & Package
The MAX11160EUB+T is housed in a 10-pin µMAX package (3mm × 3mm, 0.8mm height, 0.5mm pitch), compatible with industry-standard footprint requirements and reflow assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Analog supply input | 5V single supply for analog core; powers internal reference and ADC circuitry. |
| VSS | Analog ground | Return path for analog signals and reference; must be separated from digital ground per layout guidelines. |
| REF | Reference output/input | Provides 4.096V internal reference; can be overdriven externally to set custom VREF ≤ VDD. |
| IN+ | Pseudo-differential input positive | Accepts 0V to VREF input signal; common-mode voltage fixed at VREF/2. |
| IN– | Pseudo-differential input negative | Fixed at VREF/2; not user-accessible as independent node - defines common-mode point. |
| CS | Chip select | Active-low SPI frame synchronization; initiates conversion and data readback sequence. |
| DIN | Serial data input | Accepts command bits (e.g., unipolar/bipolar mode, power-down) during CS assertion. |
| DOUT | Serial data output | MSB-first 16-bit conversion result; valid on SCLK falling edge per SPI timing spec. |
| SCLK | Serial clock | Master-generated clock up to 25MHz; controls bit transfer rate and conversion timing alignment. |
| CONVST | Conversion start | Edge-triggered input to initiate sampling; optional alternative to CS-controlled auto-conversion mode. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline latency | Zero-cycle conversion delay enables immediate feedback in closed-loop control systems. |
| Internal reference trimming | Factory-trimmed 5ppm/°C drift eliminates need for external reference IC and associated PCB area. |
| Pseudo-differential input | Rejects common-mode noise on IN+/IN– while simplifying front-end driver design versus fully differential topology. |
| Wide digital supply range | 2.3V–5V operation avoids level shifters when interfacing with 3.3V or 5V microcontrollers and FPGAs. |
| Shutdown current | 1µA quiescent draw extends battery life in intermittent-sampling portable instruments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8860IDRCT | 16-bit, 1MSPS, 3.3V-only digital supply, no internal reference (requires external REF5040) | Higher speed but demands additional reference IC and tighter layout for noise-sensitive 1MSPS operation | Select when throughput >500ksps is required and board space permits external reference integration. |
| AD7960BCPZ-RL7 | 18-bit, 5MSPS, requires external 5V reference and separate analog/digital supplies; LVDS interface | Targeted at high-speed imaging and spectral analysis where resolution and speed outweigh size/power constraints | Choose only if 18-bit ENOB and 5MSPS are mandatory; incompatible with single-supply, low-pin-count designs. |
Compared with ADS8860IDRCT and AD7960BCPZ-RL7, the MAX11160EUB+T uniquely integrates a low-drift reference and operates from a single 5V analog rail, reducing BOM count and layout complexity for space-constrained industrial DAQ nodes where 500ksps and 16-bit integrity are optimal trade-offs.

FAQ
What is the maximum recommended operating temperature for the MAX11160EUB+T?
The MAX11160EUB+T is specified for operation from –40°C to +85°C ambient temperature. Its internal reference maintains 5ppm/°C drift across this full range, and all AC specifications-including 92.5dB SINAD and –105dB THD-are guaranteed at +85°C. Thermal derating is not required within this envelope, making the MAX11160EUB+T suitable for uncooled industrial enclosures and outdoor sensor housings.
Does the MAX11160EUB+T require an external reference, and what is its default reference voltage?
No, the MAX11160EUB+T does not require an external reference-it integrates a factory-trimmed 4.096V bandgap reference with 5ppm/°C drift. The REF pin outputs this voltage and may be overdriven with an external reference up to VDD (5V) if higher precision or custom scaling is needed. Default operation uses the internal reference, eliminating two passive components and 2–3 mm² PCB area.
What digital interface protocols does the MAX11160EUB+T support, and what are the voltage compatibility limits?
The MAX11160EUB+T supports SPI, QSPI, MICROWIRE®, and DSP-compatible serial interfaces. Its digital I/O pins (CS, DIN, DOUT, SCLK) operate from 2.3V to 5V logic levels-enabling direct connection to 2.5V, 3.3V, or 5V microcontrollers without level shifters. Clock rates up to 25MHz are supported, and data is MSB-first with DOUT valid on SCLK falling edges.
How does the pseudo-differential input architecture of the MAX11160EUB+T differ from fully differential inputs?
The MAX11160EUB+T uses a pseudo-differential input: IN+ accepts 0V to VREF, while IN– is internally fixed at VREF/2 and not externally accessible. This rejects common-mode noise on the signal path without requiring matched dual-op-amp drivers. Unlike fully differential topologies, it avoids phase-matching concerns and halves the channel count for single-ended sensor outputs, simplifying front-end design while retaining 16-bit monotonicity.
Can the MAX11160EUB+T be used in battery-powered applications, and what is its lowest power state?
Yes, the MAX11160EUB+T is optimized for battery-powered use: it draws 34mW at full 500ksps operation and enters a 1µA shutdown mode when CONVST and CS are deasserted. In shutdown, the internal reference remains off, minimizing leakage. Wake-up time is under 1µs, allowing rapid sampling bursts-ideal for energy-harvesting sensors and portable diagnostic tools relying on intermittent high-resolution capture.
