Product details
Overview
MAX1167BEEE+ from Maxim Integrated is a 4-channel, 16-bit successive-approximation analog-to-digital converter (ADC) with integrated +4.096V reference, internal oscillator, and SPI/QSPI/MICROWIRE-compatible serial interface. It operates from a single +5V analog supply and supports digital logic levels from +2.7V to +5.25V. Its 200ksps sampling rate, ±3 LSB INL, and -40°C to +85°C extended temperature range make it suitable for industrial I/O modules and thermocouple measurement systems.
For engineers reviewing the MAX1167BEEE+ datasheet, MAX1167BEEE+ pinout, MAX1167BEEE+ application, or MAX1167BEEE+ equivalent, key selection considerations include its 4-channel multiplexer architecture, internal reference accuracy (±25 ppm/°C), AutoShutdown™ current reduction to 185µA at 10ksps, and QSOP-16 package compatibility with space-constrained control systems.
Technical Context
The MAX1167BEEE+ implements a successive-approximation register (SAR) ADC core with integrated track-and-hold (4MHz input bandwidth) and programmable scan mode for sequential or continuous channel conversion. Its internal +4.096V reference features ±25 ppm/°C temperature coefficient and 5ms wake-up time after power-down.
It supports both external clock (up to 9MHz SCLK) and internal oscillator (3.2–4.0MHz) operation, with timing-critical parameters including 729ns acquisition time, 3.75μs conversion time, and strict setup/hold requirements for DIN, CS, and SCLK signals across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with no missing codes over full temperature range |
| Sampling Rate | 200ksps maximum with external clock; enables real-time motor control loop sampling |
| INL | ±3 LSB max; ensures <0.05% full-scale linearity error in precision sensor interfaces |
| Reference | +4.096V internal (±25 ppm/°C); eliminates external reference component and layout area |
| Supply Current | 3.6mA at 200ksps (AVDD = DVDD = +5V); reduces thermal load in dense PCB layouts |
| Operating Temp | -40°C to +85°C; qualified for industrial process control environments |
| Interface | SPI/QSPI/MICROWIRE-compatible 3-wire serial; interoperable with standard microcontroller peripherals |
Pinout & Package
MAX1167BEEE+ is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch) with exposed pad for thermal performance. Pin functions are validated per Maxim's official pin description table for MAX1167.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DOUT | Serial data output | MSB-first unipolar output; high-impedance when CS = high - enables bus sharing |
| SCLK | Serial clock input | Drives conversion and clocks data out; supports up to 9MHz for fast throughput |
| DIN | Serial command input | Configures scan mode, channel selection, and power-down state via command register |
| EOC | End-of-conversion flag | Active-low pulse in internal clock mode; indicates result ready at DOUT |
| AIN0–AIN3 | Analog input channels | Four single-ended inputs; 0V to VREF range supports thermocouple and accelerometer signals |
| REF / REFCAP | Reference voltage node | REF accepts external reference or outputs internal +4.096V; REFCAP requires 0.1µF bypass for stability |
| AGND / DGND | Analog/digital ground | Separate ground pins minimize noise coupling between analog and digital sections |
| AVDD / DVDD | Analog/digital supplies | Independent +5V analog and +2.7V to +5.25V digital supplies enable mixed-voltage system interfacing |
| CS | Chip-select input | Active-low control; high state forces full shutdown (0.6µA), enabling ultra-low-power sleep modes |
Key Features
| Feature | Design Value |
|---|---|
| AutoShutdown™ | Reduces current to 185µA at 10ksps and <10µA at lower rates - extends battery life in portable DAQ |
| Integrated reference | +4.096V ±0.8% initial accuracy with 5ms wake-up - eliminates calibration overhead and BOM cost |
| Scan mode | Sequential conversion of all 4 channels or continuous sampling of one channel - simplifies firmware for multi-sensor polling |
| Input protection | Clamp diodes allow AIN_ swing from (AGND − 0.3V) to (AVDD + 0.3V) - enhances robustness in noisy industrial environments |
| Track/Hold bandwidth | 4MHz small-signal input bandwidth - supports undersampling of RF or transient signals without aliasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit multichannel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8325IPW | 16-bit, 100ksps, 8-channel, SPI interface; no internal reference; requires external +2.5V ref | Higher channel count but lower speed; suited for slower, higher-density sensor arrays | Select when needing >4 channels and external reference already present in design |
| AD7682BCPZ | 16-bit, 250ksps, 4-channel, SPI interface; internal 2.5V ref; ±1.5 LSB INL; LFCSP-20 package | Better linearity and higher speed, but smaller package limits thermal dissipation in high-ambient environments | Select when prioritizing accuracy (<±2 LSB) and board area over extended temperature qualification |
Compared with ADS8325IPW and AD7682BCPZ, the MAX1167BEEE+ offers guaranteed -40°C to +85°C operation with integrated +4.096V reference and AutoShutdown™, making it optimal for industrial field instruments where reference stability, temperature resilience, and low standby power are critical.

FAQ
What is the maximum sampling rate of the MAX1167BEEE+?
The MAX1167BEEE+ achieves a maximum sampling rate of 200ksps when using an external clock source. This rate is confirmed in the Electrical Characteristics table under "Sample Rate" with fSCLK = 4.8MHz and 24 clocks per conversion. At this rate, the device consumes 3.6mA total supply current with AVDD = DVDD = +5V, and maintains ±3 LSB INL performance across the -40°C to +85°C operating range.
Does the MAX1167BEEE+ require an external reference voltage?
No, the MAX1167BEEE+ does not require an external reference voltage because it integrates a precision +4.096V reference with ±25 ppm/°C temperature coefficient and 5ms wake-up time. The REF pin can be used as either reference output (internal mode) or input (external mode), and REFCAP must be bypassed with a 0.1µF capacitor when using the internal reference. External reference operation supports 3.8V to AVDD − 0.2V.
How many analog input channels does the MAX1167BEEE+ support?
The MAX1167BEEE+ supports four single-ended analog input channels (AIN0 through AIN3), as specified in the Ordering Information table and Pin Description section. This 4-channel multiplexer architecture is fixed for the MAX1167 family; the MAX1168 variant supports eight channels. Channel selection is controlled via the command/configuration register using the DIN interface.
What package type is used for the MAX1167BEEE+?
The MAX1167BEEE+ is packaged in a 16-pin QSOP (Quarter-Size Outline Package) with dimensions 5.3mm × 10.2mm and 0.65mm lead pitch. This package is explicitly listed in the Ordering Information table for MAX1167BEEE+, and the pin configuration matches the MAX1167 functional diagram and pin description. The exposed pad version is not used - standard QSOP construction applies.
Can the MAX1167BEEE+ operate with a 3.3V digital supply?
Yes, the MAX1167BEEE+ supports digital supply voltages from +2.7V to +5.25V on the DVDD pin, making it fully compatible with 3.3V logic systems. The datasheet specifies VIH = 0.7 × DVDD and VIL = 0.3 × DVDD, ensuring reliable interface with 3.3V microcontrollers. Analog supply (AVDD) remains fixed at +4.75V to +5.25V, enabling independent analog/digital domain optimization.
